Description
M/A-COM's SW65-0440 is a GaAs MMIC absorptive
SP4T switch with an integral silicon ASIC driver. This
device is in a 24-lead plastic package. This switch offers
excellent broadband performance and repeatability from DC
to 3 GHz, while maintaining low DC power dissipation.
The SW65-0440 is ideally suited for wireless infrastructure
applications.
