Product Description

SPA-1218

1960 MHz 1 Watt Power Amplifier

with Active Bias

Sirenza Microdevices’ SPA-1218 is a high efficiency GaAs

Heterojunction Bipolar Transistor (HBT) amplifier housed in

a low-cost surface-mountable plastic package. These HBT

amplifiers are fabricated using molecular beam epitaxial

growth technology which produces reliable and consistent

performance from wafer to wafer and lot to lot.

This product is specifically designed for use as a driver

amplifier for infrastructure equipment in the 1960 MHz PCS

band. Its high linearity makes it an ideal choice for multi-carrier

and digital applications.
