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. Generated noise is typical of
switching DC-DC Converters
3. Connections and external components shown in func-
tional schematic are required. 0.1 µF Capacitors need to
be located near pins 30 & 32.
4. The exposed pad centered on the package bottom must
be connected to RF and DC ground. (For PQFN Pack-
ages)
