CXM3512EQ Datasheet, PDF (1/13 Pages) Sony Corporation – SP9T GSM/UMTS Dual Mode Antenna Switch
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.
* L.F.M. = Lead Frame Module
(Applications: GSM (4 bands) / UMTS (3 bands, class I-VI) or CDMA (2 bands) dual-mode handset)
