Description
M/A-COM鈥檚 SW-277 is a GaAs MMIC SPDT switch in a low cost
SOIC 8-lead surface mount plastic package. The SW-277 is ideally
suited for use where very low power consumption is required.
Typical applications include transmit/receive switching,
switch matrices, and 鏗乴ter banks in systems such as: radio and
cellular equipment, PCM, GPS, 鏗乥er optic modules, and other
battery powered radio equipment.
The SW-277 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 鈥淭ape and Reel Packaging鈥?Section, or contact factory.
2. All speci鏗乧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鏗乪d. High power (greater than 1W) handling speci鏗乧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 pack-
age from ground or any other voltage.
