Description
M/A-COM’s SW-277 is a GaAs MMIC SPDT switch
in a low cost 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.
