Description
M/A-COM's SW-314 is a GaAs MMIC SP4T absorptive
switch with an integral silicon ASIC driver. This
device is in a 24-lead ceramic surface mount package.
These switches exhibit excellent performance from DC to 3
GHz, with very low DC power dissipation. The
SW-314 is ideally suited for RF/IF communications
applications. Environmental screening is available.
Contact the factory for information.
