Description

M/A-COM’s MASWSS0040 is a GaAs pHEMT

MMIC DPDT diversity switch in a low cost miniature

3 mm 12-lead PQFN package. The MASWSS0040

is ideally suited for applications where very small

size and low cost are required.

Typical applications are for WLAN IEEE 802.11b/g

systems that employ two antennas for transmit and

receive diversity.

This part is designed for low

insertion loss and allows for independent control and

selection of each switch path. This part can be used

in all systems operating up to 3.0 GHz requiring

moderate power and diversity switching.

The MASWSS0040 is fabricated using a 0.5 micron

gate length GaAs pHEMT process.
