2. Electrical Properties 2.1 Frequency Band Service GSM850 GSM900 DCS1800 PCS1900 Band Tx(MHz) 824 ~ 849 880 ~ 915 1710 ∼ 1785 1850 ~ 1910 Rx(MHz) 869 ~ 894 925 ~ 960 1805 ∼ 1880 1930 ~ 1990 2.2 Impendance 2.2.1 Normal Value 50Ω ± 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 2.3.1 Maximum values in free space Service GSM850 GSM900 DCS1800 PCS1900 VSWR Tx Rx Tx Rx Tx Rx Tx Rx VSWR 5.9:1 2.4:1 3.1:1 2.4:1 8.6:1 3.5:1 4.5:1 2.4:1 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 produced handset, 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. The free space means that the handset is placed on a non-conductive surface of cellular plastic. Company Confidential Proprietary 4/15
