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.

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 30 & 32.
