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.

Operation of this device above any one of these
parameters may cause permanent damage.
When the RF input is applied to the terminated port, the
absolute maximum power is +30 dBm.
Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
