Description

M/A-COM’s SW-311 is a GaAs FET SPST absorptive
switch with integral silicon ASIC driver. Packaged in a
16-lead ceramic surface mount package, this device offers
excellent performance and repeatability from DC to 3 GHz
while maintaining low power consumption. The
SW-311 is ideally suited for use where fast speed, low
power consumption and broadband applications are
required. MIL-STD-883 Screening Available.
