Description

M/A-COM's SW90-0002 is a SPDT 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
SW90-0002 is ideally suited for wireless infrastructure
applications.

1. NC = No Connection

2. VEE is internally generated and must remain isolated from
external power supplies.

3. Connections and external components shown in functional
schematic are required. 0.1 µF Capacitors need to be
located near pins 20 & 26.
