Description

M/A-COM’s MASWSS0118 is a GaAs PHEMT

MMIC single pole four throw (SP4T) high power

switch in a low cost 4 mm 16-lead PQFN package.

The MASWSS0118 is ideally suited for applications

where high power, low control voltage, low insertion

loss, high isolation, small size, and low cost are

required.

Typical applications are for GSM and DCS handset

systems that connect separate transmit and receive

functions to a common antenna, as well as other

handset and related applications. This part can be

used in all systems operating up to 3.0 GHz

requiring high power at low control voltage.

The MASWSS0118 is fabricated using a 0.5 micron

gate length GaAs PHEMT process. The process

features full passivation for performance and

reliability.
