Description

The 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 Technology fabricates the MASWSS0178

using a 1.0-micron gate length MESFET process.

The process features full chip passivation for

performance and reliability.
