                           Type: D2450V2

                     Manufactured:              September 10, 2002
                            Calibrated:         August 23, 2004


4        Measurement Conditions


The measurements were performed in the quarter size flat phantom filled with head simulating
solution ofthe following electrical parameters at 2450 MHz:

         Relative Diclectricity                 38.3         + 5%
         Conductivity                           1.86 mho/m     £5%

The DASY4 System with a dosimetric E—field probe ES3DV2 (SN:3025, Conversion factor 4.55 at
2450 MHz) was used for the measurements.

The dipole was mounted on the small tripod so thatthe dipole feedpoint was positioned below the
center marking of the quarter size flat phantom and the dipole was oriented parallel to the body axis
(the long side ofthe phantom). The standard measuring distance was 10mm from dipole center to the
solution surface. Lossless spacer was used during measurements for accurate distance positioning.

The coarse grid with a grid spacing of 15mm was aligned with the dipole. The 7x7x7 fine cube was
chosen for cube integration.
The dipole input power (forward power) was 250mW + 3 %. The results are normalized to 1 W input
power.



2        SAR Measurement with DASY4 System

Standard SAR—measurements were performed according to the measurement conditions described in
section 1. The results (see figure supplied) have been normalized to a dipole input power of 1 W
(forward power). The resulting averaged SAR—values measured with the dosimetric probe ES3DV2
SN:3025 and applying the advanced extrapolation are:


         averaged over 1 om‘ (1 g) of tissue:          52.4 mWig + 16.8 % (k:2)'

         averaged over 10 cm‘ (10 g) of tissue:        23.8 mWig + 16.2 % (k:72)l

3.     Dipole Impedance and Return Loss

The impedance was measured at the SMA—connector with a network analyzer and numerically
transformed to the dipole feedpoint. The transformation parameters from the SMA—connector to the
dipole feedpoint are:

      Electrical delay:          1.147 ns   (one direction)
      Transmission factor:       0.983      (voltage transmission, one direction)


The dipole was positioned at the flat phantom sections according to section 1 and the distance spacer
was in place during impedance measurements.


       Feedpoint impedance at 2450 MHz:              Re{Z} = 54.7 0

                                                     Im {Z} =2.7 0

       Return Loss at 2450 MHz                       —26.1 dB




4.     Measurement Conditions

The measurements were performed in the quarter size flat phantom filled with body simulating
solution of the following electrical parameters at 2450 MHz:

       Relative Dielectricity                51.7       +5%
       Conductivity                          1.96 mho/m £5%

The DASY4 System with a dosimetric E—field probe ES3DV2 (SN:3025, Conversion factor 4.22 at
2450 MHz) was used for the measurements.

The dipole was mounted on the small tripod so that the dipole feedpoint was positioned below the
center marking of the quarter size flat phantom and the dipole was oriented parallelto the body axis (the
long side of the phantom). The standard measuring distance was 10mm from dipole center to the
solution surface. Lossless spacer was used during measurements for accurate distance positioning.

The coarse grid with a grid spacing of 15mm was aligned with the dipole. The 7x7x7 fine cube was
chosen for cube integration.
The dipole input power (forward power) was 250mW +3 %. The results are normalized to 1 W input
power.


5.       SAR Measurement with DASY4 System

Standard SAR—measurements were performed according to the measurement conditions described in
section 4. The results (see figure supplied) have been normalized to a dipole input power of I W
(forward power). The resulting averaged SAR—values measured with the dosimetric probe ES3DV2
SN:3025 and applying the advanced extrapolation are:


         averaged over 1 em‘ (1 g) of tissue:         48.8 mW/g + 16.8 % (&2)

         averaged over 10 em‘ (10 g) of tissue:       22.6 mWig + 16.2 % (IFZ)Z



6.       Dipole Impedance and Return Loss

The dipole was positioned at the flat phantom sections according to section 4 and the distance spacer
was in place during impedance measurements.


         Feedpoint impedance at 2450 MHz:             Re{Z} = 50.8 0

                                                      Im {Z} = 4.1 0

         Return Loss at 2450 MHz                      —27.1 dB



7        Handling

Do not apply excessive force to the dipole arms, because they might bend. Bending ofthe dipole arms
stresses the soldered connections near the feedpoint leading to a damage ofthe dipole.


8.       Design

The dipole is made ofstandard semirigid coaxial cable. The center conductor ofthe feeding line is
directly connected to the second arm ofthe dipole. The antennais therefore short—circuited for DC—
signals.

Small end caps have been added to the dipole arms in order to improve matching when loaded
according to the position as explained in Sections land 4. The SAR data are not affected bythis change.
The overall dipole length is still according to the Standard.


9.       Power Test

After long term use with 40W radiated power, only a slight warming of the dipole near the feedpoint
can be measured.
