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.

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.
