Description
M/A-COM’s MASWSS0020 is a GaAs PHEMT MMIC
single pole four throw (SP4T) high power switch in a low
cost miniature FQFP 16-lead 4x4mm package. The
MASWSS0020 is ideally suited for applications where high
power, low control voltage, low insertion loss, high isola-
tion, small size and low cost are required. Typical applica-
tions are for GSM and DCS handset systems that connect
separate transmit and receive functions to a common an-
tenna, as well as other handset and related applications.
This part can be used in all systems operating up to 3 GHz
requiring high power at low control voltage.
The MASWSS0020 is fabricated using a 0.5 micron gate
length GaAs PHEMT process. The process features full
passivation for performance and reliability.
