Description

M/A-COM’s SW-259 is a GaAs MMIC SPST terminated switch

in a low cost SOIC 8-lead surface mount plastic package.

The SW-259 is ideally suited for use where very low power

consumption is required. Typical applications include trans-

mit/receive switching, switch matrices, and filter banks in

systems such as: radio and cellular equipment, PCM, GPS,

fiber optic modules, and other battery powered radio

equipment.

The SW-259 is fabricated with a monolithic GaAs MMIC

using a mature 1-micron process. The process features full

chip passivation for increased performance and reliability.

1. Refer to "Tape and Reel Packaging" Section, or contact factory.

2. All measurements with 0, -5 control voltages at 1 GHz in a 50

Ω system, unless otherwise specified.
