Description
M/A-COM’s MASWSS0157 is a GaAs MMIC SPDT
switch in a lead-free SOIC 8-lead surface mount
plastic package. The MASWSS0157 is ideally suited
for use where low power consumption is required.
Typical applications include transmit/receive
switching, switch matrices and switched filter banks
in systems such as radio and cellular equipment,
PCM, GPS, fiber optic modules, and other battery
powered radio equipment.
The MASWSS0157 is fabricated using a monolithic
GaAs MMIC using a mature 1 micron process. The
process features full chip passivation for increased
performance and reliability.
