1. General 1.1 The Product Model Name Antenna Type Magnetic Applications CDMA 800MHz, 1900MHz 1.2 Electrical Properties Frequency Range(Tx) 824~849 MHz, 1850~1910 MHz Frequency Range(Rx) 869~894 MHz, 1930~1990 MHz Impedance 30Ω ± 10Ω VSWR Less Than 3.0:1 Radiation Pattern Omni-Directional Polarization Linear 1.3 Mechanical Properties Dimension 20.0 mm(L) x 6.5 mm(W) x 6.5 mm(H) Operational Temperature -20°C ~ +70°C Cable length 1m Ground plate 120(mm) x 180(mm) Confidential Proprietary 3/16

2. Electrical Properties 2.1 Frequency Band Service CDMA800 CDMA1900 Band Tx(MHz) 824~849 1850~1910 Rx(MHz) 869~894 1930~1990 2.2 Impedance 2.2.1 Normal Value 30Ω ± 10Ω 2.2.1 Measuring Method The impedance over the frequency bands shall be as close as possible to 50Ω after matching. Both free space and talk position are considered. 2.3 VSWR The impedance matching should be optimized in the more critical talk position. 2.3.1 Maximum values in free space CDMA 800 MHz CDMA 1900 MHz SERVICE TX RX TX RX VSWR 3.0:1 2.5:1 3.0:1 2.5:1 2.3.2 Measuring Method A 50Ω coaxial cable is connected(soldered) to the 50Ω point, at the duplex- filter on the main PCB. The connection of the coaxial cable shall be done to introduce a minimum of mismatch. As much as possible the coaxial cable arrangement shall prevent influences from induced currents on the cable. In the other end, the coaxial cable is connected to a network analyzer. The measurement is performed at room temperature. The handset, including the PCB, must not in any significant way differ from the mass production, i.e. the antenna feeding network has to be equivalent to the feeding network in mass production. The specification shall be met in the entire frequency band. Confidential Proprietary 4/16

The antenna is taken out after 1 hour, and VSWR is immediately measured. The antenna is placed in a climatic chamber at temperature THO. The antenna is taken out after 1 hour, and VSWR is immediately measured. 3.2 Temperature Cycling 3.2.1 Low Cycling Temperature TLC = -40°C 3.2.2 High Cycling Temperature THC = +80°C 3.2.3 Demands No visual deterioration shall occur during the test. The antenna shall satisfy the electrical demands, according to 2.4.1. 3.2.4 Measuring Method The antenna is placed in a climatic chamber. The temperature is cycled as follows : The temperature is kept constantly at TLC for 1 hour, increased to THC during 1 hour, kept constantly at THC for 1 hour, and then decreased to TLC during 1 hour. This procedure is repeated 10 times, ending at room temperature according to figure 3 below. Figure 3. Temperature Cycling Confidential Proprietary 8/16
