Description
M/A-COM’s SW-277 is a GaAs MMIC SPDT switch
in a SOIC-8 lead surface mount plastic package.
The SW-277 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 SW-277 is fabricated using a monolithic GaAs
MMIC using a mature 1 micron process. The
process features full chip passivation for increased
performance and reliability.
