Description

M/A-COM’s SW-283-PIN is a GaAs MMIC transfer

switch packaged in lead-free, surface mount CR-4

ceramic style packages. SW-283-PIN offers low

insertion loss, high isolation, and fast switching.

This ceramic switch platform has a common footprint

for all three designs. The CR-4 package is hermeti-

cally sealed, making this switch ideal for space, mili-

tary radios, and other environmentally harsh applica-

tions.

Typical applications include synthesizer switching,

transmit/receive switching, switch matrices and filter

banks in systems such as radio and cellular equip-

ment, PCM, GPS, and fiber optic modules.

The SW-283-PIN transfer switch contains a mono-

lithic GaAs MMIC which is fabricated using a 1.0

micron MESFET process.
