Description

M/A-COM’s SW-226/227/228-PIN are GaAs MMIC

SPDT switches packaged in lead-free, surface

mount CR-2 ceramic style packages. The SW-226-

PIN is a terminated SPDT. The SW-227-PIN offers

high isolation. The SW-228-PIN offers low insertion

loss. This ceramic switch platform has a common

footprint for all three designs. The CR-2 package is

hermetically sealed, making these switches ideal for

space, military radios, and other environmentally

harsh applications.

Typical applications include synthesizer switching,

transmit/receive switching, switch matrices and filter

banks in systems such as radio and cellular

equipment, PCM, GPS, and fiber optic modules.

The SW-226/227/228-PIN are fabricated as mono-

lithic GaAs MMICs using a 1.0 micron MESFET

process.
