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.
