M/A-COM’s SW-279 is a GaAs MMIC SPDT switch in a low cost
SOIC 8-lead surface mount plastic package. The SW-279 is ideally suited for use where very low power consumption is
required. Typical applications include transmit/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.

1. Refer to “Tape and Reel Packaging” Section, or contact factory.
2. All specifications apply when operated with bias voltages of 0V for Vin Low and 5 to 10V for Vin Hi, and 50 Ohm impedance at all RF ports,
unless otherwise specified. High power (greater than 1W) handling specifications apply to cold switches only. For input powers under 1W, hot
switching can be used. The high control voltage must be within +/- 0.2V of the supply voltage. The RF ports must be blocked outside of the
package from ground or any other voltage.
Specifications Subject to Change Without Notice.
