Description

The M/A-COM SW-475 GaAs monolithic switch

provides high isolation in a low-cost, plastic surface

mount package.

The SW-475 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 SW-475 using a 1.0-micron

gate length MESFET process. The process features

full chip passivation for performance and reliability.
