Description

The M/A-COM MASWSS0121 GaAs monolithic

switch provides high isolation in a low-cost, lead-free

plastic surface mount package. The MASWSS0121

is ideal for applications across a broad range of

frequencies

including

synthesizer

switching,

transmit / receive switching, switch matrices and

filter banks in systems such as radio and cellular

equipment, PCS, GPS, and fiber optic modules.

M/A-COM fabricates the MASWSS0121 using a 1.0-

micron gate length MESFET process. The process

features full chip passivation for performance and

reliability.
