Description
M/A-COM’s SW-289 is a GaAs MMIC DPDT switch in a low cost
SOIC 14-lead surface mount plastic package. The SW-289 is ideally
suited for use where very low power consumption is required.
Typical applications include transmit/receive switching, switch
matrices, digital step attenuators, and filter banks in systems such as:
radio and cellular equipment, PCM, GPS, fiber optic modules, and
other battery powered radio equipment.
Ordering Information
The SW-289 is fabricated with a monolithic GaAs MMIC using a
mature 1-micron process. The process features full chip passivation
for increased performance and reliability.
