Description

The MASWSS0157 is a GaAs MMIC SPDT switch in

a lead-free SOIC 8-lead surface mount plastic

package. This device 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 MASWSS0157 is fabricated using a monolithic

GaAs MMIC using a mature 1 micron process. The

process features full chip passivation for increased

performance and reliability.
