Description

M/A-COM’s SW-243 GaAs MMIC SP4T switch is

packaged in a CR-4 surface mount ceramic style

package.

The SW-243 is a reflective switch,

optimized for low insertion loss. The CR-4 package

is hermetically sealed, making these switches ideal

for space, military radios, or other environmentally

harsh applications.

Typical applications include synthesizer switching,

switch matrices and filter banks in systems such as

military radios, and space equipment.

The SW-243 is fabricated as a monolithic GaAs

MMIC using a 1.0 micron MESFET process.
