Description

M/A-COM's SW90-0003 is a SP4T 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
SW90-0003 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. 0.1µF Capacitors need to be lo­cated near pins 32 & 33.
