10.1.1Frequency Band
Frequency Band
CDMA 850 CDMA 1900
TX 824 ~ 849 1850 ~ 1910
RX 869 ~ 894 1930 ~ 1990
10.1.2 Normal value
50Ω ± Normal
10.1.3 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.
10.2 VSWR
The impedance matching should be optimized in the more critical talk position.
