2.30 GHz – 2.40 GHz
50 Watt High Power SPDT Switch with LNA Module
Data Sheet
Description
Avago Technologies’ ALM-12224 is a multi-chip integrated
module that comprise of a 50 Watt CW high power SPDT
switch, 1
gain driver amplifi er through the use of Avago Tech-
nologies’ proprietary 0.25um GaAs Enhancement-mode
pHEMT process and low distortion silicon PIN diode
technologies.
The ALM-12224 is housed in a compact 8.0 x 8.0 x 1.2 mm
molded-chips-on-board (MCOB) module package with 24
pin confi guration pads, off ering signifi cant PCB space saving
as compare to conventional discrete design approach.
The device off ers high power protection switch (Tx mode
operation) with very low insertion loss. During Rx mode
operation, the receiver chain provides a very low NF and
high gain that makes it an ideal choice for cellular infra-
structure in TD-LTE applications.
