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.
Pin 1
Pin Configuration
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.
