Preliminary

Product Description

SPA-1218

Stanford 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.

1960 MHz 1 Watt Power Amp with

Active Bias

This product is specifically designed for use as a driver

amplifier for infrastructure equipment in the 1950 MHz PCS

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

and digital applications.
