DEVICE HOLDER FOR SAM TWIN PHANTOM CONSTRUCTION The device holder for the mobile phone device is designed to cope with different positions given in the standard. It has two scales for the device rotation (with respect to the body axis) and the device inclination (with respect to the line between the ear reference points). The rotation centers for both scales is the ear reference point (ERP). Thus the device needs no repositioning when changing the angles. The holder has been made out of low-loss POM material having the following dielectric parameters: relative permittivityε=3 and loss tangent δ=0.02. The amount of dielectric material has been reduced in the closest vicinity of the device, since measurements have suggested that the influence of the clamp on the test results could thus be lowered. The device holder for the portable device makes up of the polyethylene foam. The dielectric parameters of material close to the dielectric parameters of the air. DATA ACQUISITION ELECTRONICS CONSTRUCTION The data acquisition electronics (DAE3) consists of a highly sensitive electrometer grade preamplifier with auto-zeroing, a channel and gain-switching multiplex, a fast 16 bit AD converter and a command decoder and control logic unit. Transmission to the measurement server is accomplished through an optical downlink for data and status information as well as an optical uplink for commands and the clock. The mechanical probe is mounting device includes two different sensor systems for frontal and sideways probe contacts. They are used for mechanical surface detection and probe collision detection. The input impedance of the DAE3 box is 200MOhm; the inputs are symmetrical and floating. Common mode rejection is above 80 dB.

2.5 GENERAL DESCRIPTION OF THE SPATIAL PEAK SAR EVALUATION The DASY4 post-processing software (SEMCAD) automatically executes the following procedures to calculate the field units from the micro-volt readings at the probe connector. The parameters used in the evaluation are stored in the configuration modules of the software: Probe parameters: - Sensitivity Normi, ai0, ai1, ai2 - Conversion factor ConvFi - Diode compression point dcpi Device parameters: - Frequency F - Crest factor Cf Media parameters: - Conductivity σ - Density ρ The first step of the evaluation is a linearization of the filtered input signal to account for the compression characteristics of the detector diode. The compensation depends on the input signal, the diode type and the DC-transmission factor from the diode to the evaluation electronics. If the exciting field is pulsed, the crest factor of the signal must be known to correctly compensate for peak power. The formula for each channel can be given as: cf Vi = U i + U i • 2 dcp i Vi =compensated signal of channel i (i = x, y, z) Ui =input signal of channel I (i = x, y, z) Cf =crest factor of exciting field (DASY parameter) dcpi =diode compression point (DASY parameter) Report No.: SA990816E05A 10 Report Format Version 3.0.1 Reference No.: 991011E08

From the compensated input signals the primary field data for each channel can be evaluated: V1 E-fieldprobes: Ei = Normi ⋅ ConvF ai 0 + ai1 f + ai 2 f 2 H-fieldprobes: H i = Vi ⋅ f Vi =compensated signal of channel I (i = x, y, z) Normi =sensor sensitivity of channel i µV/(V/m)2 for (i = x, y, z) E-field Probes ConvF = sensitivity enhancement in solution aij = sensor sensitivity factors for H-field probes F = carrier frequency [GHz] Ei = electric field strength of channel i in V/m Hi = magnetic field strength of channel i in A/m The RSS value of the field components gives the total field strength (Hermitian magnitude): E tot = E x2 + E y2 + E z2 The primary field data are used to calculate the derived field units. σ SAR = E tot 2 ⋅ ρ ⋅ 1'000 SAR = local specific absorption rate in mW/g Etot = total field strength in V/m σ = conductivity in [mho/m] or [Siemens/m] ρ = equivalent tissue density in g/cm3 Report No.: SA990816E05A 11 Report Format Version 3.0.1 Reference No.: 991011E08

Note that the density is set to 1, to account for actual head tissue density rather than the density of the tissue simulating liquid. The entire evaluation of the spatial peak values is performed within the Post-processing engine (SEMCAD). The system always gives the maximum values for the 1g and 10g cubes. The algorithm to find the cube with highest averaged SAR is divided into the following stages: 1. The extraction of the measured data (grid and values) from the Zoom Scan 2. The calculation of the SAR value at every measurement point based on all stored data (A/D values and measurement parameters) 3. The generation of a high-resolution mesh within the measured volume 4. The interpolation of all measured values from the measurement grid to the high-resolution grid 5. The extrapolation of the entire 3-D field distribution to the phantom surface over the distance from sensor to surface 6. The calculation of the averaged SAR within masses of 1g and 10g. The probe is calibrated at the center of the dipole sensors that is located 1 to 2.7mm away from the probe tip. During measurements, the probe stops shortly above the phantom surface, depending on the probe and the surface detecting system. Both distances are included as parameters in the probe configuration file. The software always knows exactly how far away the measured point is from the surface. As the probe cannot directly measure at the surface, the values between the deepest measured point and the surface must be extrapolated. The angle between the probe axis and the surface normal line is less than 30 degree. Report No.: SA990816E05A 12 Report Format Version 3.0.1 Reference No.: 991011E08

The maximum search is automatically performed after each area scan measurement. It is based on splines in two or three dimensions. The procedure can find the maximum for most SAR distributions even with relatively large grid spacing. After the area scanning measurement, the probe is automatically moved to a position at the interpolated maximum. The following scan can directly use this position for reference, e.g., for a finer resolution grid or the cube evaluations. The 1g and 10g peak evaluations are only available for the predefined cube 7 x 7 x 7 scans. The routines are verified and optimized for the grid dimensions used in these cube measurements. The measured volume of 30 x 30 x 30mm contains about 30g of tissue. The first procedure is an extrapolation (incl. boundary correction) to get the points between the lowest measured plane and the surface. The next step uses 3D interpolation to get all points within the measured volume in a 1mm grid (42875 points). In the last step, a 1g cube is placed numerically into the volume and its averaged SAR is calculated. This cube is the moved around until the highest averaged SAR is found. If the highest SAR is found at the edge of the measured volume, the system will issue a warning: higher SAR values might be found outside of the measured volume. In that case the cube measurement can be repeated, using the new interpolated maximum as the center. 2.6 DESCRIPTION OF SUPPORT UNITS The EUT has been tested as an independent unit.

4. RECIPES FOR TISSUE SIMULATING LIQUIDS For the measurement of the field distribution inside the SAM phantom, the phantom must be filled with 25 litters of tissue simulation liquid.

Testing the liquids using the Agilent Network Analyzer E8358A and Agilent Dielectric Probe Kit 85070D.The testing procedure is following as 1. Turn Network Analyzer on and allow at least 30min. warm up. 2. Mount dielectric probe kit so that interconnecting cable to Network Analyzer will not be moved during measurements or calibration. 3. Pour de-ionized water and measure water temperature (±1°). 4. Set water temperature in Agilent-Software (Calibration Setup). 5. Perform calibration. 6. Validate calibration with dielectric material of known properties (e.g. polished ceramic slab with >8mm thickness ε'=10.0, ε''=0.0). If measured parameters do not fit within tolerance, repeat calibration (±0.2 for ε': ±0.1 for ε''). 7. Conductivity can be calculated from ε'' by σ = ω ε0 ε'' =ε'' f [GHz] / 18. 8. Measure liquid shortly after calibration. Repeat calibration every hour. 9. Stir the liquid to be measured. Take a sample (~ 50ml) with a syringe from the center of the liquid container. 10. Pour the liquid into a small glass flask. Hold the syringe at the bottom of the flask to avoid air bubbles. 11. Put the dielectric probe in the glass flask. Check that there are no air bubbles in front of the opening in the dielectric probe kit. 12. Perform measurements. 13. Adjust medium parameters in DASY4 for the frequencies necessary for the measurements (‘Setup Config’, select medium (e.g. Brain 900MHz) and press ‘Option’-button. 14.

5. SYSTEM VALIDATION The system validation was performed in the flat phantom with equipment listed in the following table. Since the SAR value is calculated from the measured electric field, dielectric constant and conductivity of the body tissue and the SAR is proportional to the square of the electric field. So, the SAR value will be also proportional to the RF power input to the system validation dipole under the same test environment. In our system validation test, 250mW RF input power was used. 5.1 TEST PROCEDURE Before the system performance check, we need only to tell the system which components (probe, medium, and device) are used for the system performance check; the system will take care of all parameters. The dipole must be placed beneath the flat section of the SAM Twin Phantom with the correct distance holder in place. The distance holder should touch the phantom surface with a light pressure at the reference marking (little cross) and be oriented parallel to the long side of the phantom. Accurate positioning is not necessary, since the system will search for the peak SAR location, except that the dipole arms should be parallel to the surface. The device holder for mobile phones can be left in place but should be rotated away from the dipole. 1. The ”Power Reference Measurement” and ”Power Drift Measurement” jobs are located at the beginning and end of the batch process. They measure the field drift at one single point in the liquid over the complete procedure. The indicated drift is mainly the variation of the amplifier output power. If it is too high (above ±0.1 dB), the system performance check should be repeated; some amplifiers have very high drift during warm-up. A stable amplifier gives drift results in the DASY system below ±0.02dB. 2. The ”Surface Check” job tests the optical surface detection system of the DASY system by repeatedly detecting the surface with the optical and mechanical surface detector and comparing the results. The output gives the detecting heights of both systems, the difference between the two systems and the standard deviation of the detection repeatability. Air bubbles or refraction in the liquid due to separation of the sugar-water mixture gives poor repeatability (above ±0.1mm). In that case it is better to abort the system performance check and stir the liquid. Report No.: SA990816E05A 18 Report Format Version 3.0.1 Reference No.: 991011E08

3. The ”Area Scan” job measures the SAR above the dipole on a plane parallel to the surface. It is used to locate the approximate location of the peak SAR. The proposed scan uses large grid spacing for faster measurement; due to the symmetric field, the peak detection is reliable. If a finer graphic is desired, the grid spacing can be reduced. Grid spacing and orientation have no influence on the SAR result. 4. The ”Zoom Scan” job measures the field in a volume around the peak SAR value assessed in the previous ”Area Scan” job (for more information see the application note on SAR evaluation). About the validation dipole positioning uncertainty, the constant and low loss dielectric spacer is used to establish the correct distance between the top surface of the dipole and the bottom surface of the phantom, the error component introduced by the uncertainty of the distance between the liquid (i.e., phantom shell) and the validation dipole in the DASY4 system is less than ±0.1mm. (a + d ) 2 SARtolerance [%] = 100 × ( − 1) a2 As the closest distance is 10mm, the resulting tolerance SARtolerance[%] is <2%. 5.2 VALIDATION RESULTS SYSTEM VALIDATION TEST OF SIMULATING LIQUID FREQUENCY REQUIRED MEASURED DEVIATION SEPARATION TESTED DATE (MHz) SAR (mW/g) SAR (mW/g) (%) DISTANCE MSL2450 13.10 (1g) 12.80 -2.29 10mm Oct. 13, 2010 NOTE: Please see Appendix for the photo of system validation test.

6. TEST RESULTS 6.1 TEST PROCEDURES The EUT plugged into the notebook. Use the software to control the EUT channel and transmission power. Then record the conducted power before the testing. Place the EUT to the specific test location. After the testing, must writing down the conducted power of the EUT into the report. The SAR value was calculated via the 3D spline interpolation algorithm that has been implemented in the software of DASY4 SAR measurement system manufactured and calibrated by SPEAG. According to the IEEE 1528 standards, the recommended procedure for assessing the peak spatial-average SAR value consists of the following steps: • Power reference measurement • Verification of the power reference measurement • Area scan • Zoom scan • Power reference measurement The area scan was performed for the highest spatial SAR location. The zoom scan was performed for SAR value averaged over 1g and 10g spatial volumes. Report No.: SA990816E05A 21 Report Format Version 3.0.1 Reference No.: 991011E08

In the zoom scan, the distance between the measurement point at the probe sensor location (geometric center behind the probe tip) and the phantom surface is 2mm and maintained at a constant distance of ±0.5mm during a zoom scan to determine peak SAR locations. The distance is 2mm between the first measurement point and the bottom surface of the phantom. The secondary measurement point to the bottom surface of the phantom is with 7mm separation distance. The cube size is 5 x 5 x 7 points consists of 175 points and the grid space is 8 x 8 x 5 mm. The measurement time is 0.5s at each point of the zoom scan. The probe boundary effect compensation shall be applied during the SAR test. Because of the tip of the probe to the Phantom surface separated distances are longer than half a tip probe diameter. In the area scan, the separation distance is 2mm between the each measurement point and the phantom surface. The scan size shall be included the transmission portion of the EUT. The measurement time is the same as the zoom scan. At last the reference power drift shall be less than ±5%. Report No.: SA990816E05A 22 Report Format Version 3.0.1 Reference No.: 991011E08
