| CXM3517BER [SP7T Antenna Switch Module for GSM and UMTS or CDMA Dual Mode Handset] |
>>Description
This switch is one of a range of low insertion loss, good linearity and high power MMIC antenna switch modules
for GSM/UMTS or CDMA dual-mode handsets.
The Sony A.S.M. contains SP7T switch, a 1.8V CMOS decoder and a dual-LPF on GSM transmit paths.
The Sony GaAs junction gate pHEMT (JPHEMT) process is used for very low insertion loss and high linearity.
The excellent insertion loss contributes to good sensitivity and longer talk time.
* A.S.M. = Antenna Switch Module
(Applications: Quad Band GSM and Single Band UMTS or CDMA Dual-Mode Handset) |
