Description

The M/A-COM MASWSS0178 GaAs monolithic

switch provides high isolation in a lead-free, plastic

surface mount package.

The MASWSS0178 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 MASWSS0178 using a

1.0-micron gate length MESFET process.

The

process

features

full

chip

passivation

for

performance and reliability.
