Description
M/A-COM鈥檚 SW-279 is a GaAs MMIC SPDT switch in a low cost
SOIC 8-lead surface mount plastic package. The SW-279 is ideal-
ly suited for use where very low power consumption is
required. Typical applications include transmit/receive switch-
ing, switch matrices, and 铿乴ter banks in systems such as: radio
and cellular equipment, PCM, GPS, 铿乥er optic modules, and
other battery powered radio equipment.
The SW-279 is fabricated with a monolithic GaAs MMIC using a
mature 1 micron process. The process features full chip passiva-
tion for increased performance and reliability.

1. Refer to 鈥淭ape and Reel Packaging鈥?Section, or contact factory.
2. All speci铿乧ations 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 speci铿乪d. High power (greater than 1W) handling speci铿乧ations 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.
Speci铿乧ations Subject to Change Without Notice.
