Description

M/A-COM's SW90-0001 is a SPST absorptive pHEMT

switch with integral TTL driver. This device is in an MLP

plastic surface mount package. This switch offers excellent

broadband performance and repeatability from DC to 4

GHz, while maintaining low DC power dissipation. The

SW90-0001 is ideally suited for wireless infrastructure

applications.
