Description

M/A-COM’s MASWSS0148 is a GaAs monolithic

single pole single throw (SPST) terminated switch in

a lead-free 3 mm 12-lead PQFN plastic package.

The MASWSS0148 is ideally suited for use where

low power consumption, small size and high isola-

tion are required.

Typical applications include PCS and GSM LO

switching, switch matrices and switched filter banks

in systems such as radio and cellular equipment.

The MASWSS0148 is fabricated using a mature 1-

micron gate length GaAs MESFET process. The

process features full chip passivation for increased

performance and reliability.
