SPA-2118

850 MHz 1 Watt Power Amplifier with Active Bias

Sirenza Microdevices => RFMD 

Product Description

Sirenza Microdevices’ SPA-2118 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.

SPA-2118

850 MHz 1 Watt Power Amplifier

with Active Bias

This product is specifically designed for use as a driver

amplifier for infrastructure equipment in the 850 MHz band.

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

digital applications.
