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.
