GaAs High Isolation Switch
DC - 3.0 GHz
SW-439
Description
M/A-COM's SW-439 is a GaAs MMIC SPDT switch in a low
cost MSOP-10 surface mount plastic package. This part is ideal
for high isolation, broadband switching requirements. Typical
applications include synthesizer switching, transmit/receive
switching, switch matrices and filter banks in systems such as
radio and cellular equipment, PCM, GPS, and fiber optic mod-
ules
The SW-439 is fabricated as a monolithic GaAs MMIC using a
mature 1 micron process. The process features full passivation
