SP9T GSM/UMTS Dual Mode Antenna Switch

CXM3512EQ

Description

The CXM3512EQ is one of a range of low insertion loss, high linearity, low IMD and high power MMIC antenna

switch modules for GSM/UMTS or CDMA dual-mode handsets.

The Sony L.F.M.* contains SP9T switch die, CMOS decoder and a dual-LPF on GSM transmit paths for

suppression of transmitter harmonics.

Excellent insertion loss contributes to the good sensitivity and longer talk time. This switch also provides

excellent ESD performance.
