Triple-Band GaAs IC
Antenna Switch Module
AM124
Description
The AM124 is an EGSM/DCS/PCS antenna switch
module with integrated SP2T/SP3T GaAs switches,
decoder for 3 line control, T
X
low pass filters and diplexer.
It is housed in a 13 pin 5.4 x 4.0 x 1.7 mm LTCC multilayer
ceramic package. The module has internal ESD protection
to 2000 V. For protection to 8 kV and higher, contact factory
for application note.

Material: FR4
The circuit board used in the final application should employ RF circuit design
techniques. RF signal lines should have 50
impedance. The package bottom
ground plane should be connected directly to PCB ground plane. A sufficient
number of via holes should be used to connect the top and bottom ground
planes. The evaluation circuit board shown is available upon request.
