Description
50Ω
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
isolation are required.

RFout
Typical applications include PCS and GSM LO
switching, switch matrices and switched filter banks
in systems such as radio and cellular equipment.
1. VDD can be injected at either pin 5 or pin 11.
Pin Configuration
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.
