Description
M/A-COM's SW-312 is a GaAs FET SPDT reflective
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-312 is ideally suited for use where fast speed,
low power consumption and broadband applications are
required. MIL-STD-883 screening available.
