2140 MHz 1 Watt Power Amp With Active Bias

The SPA-2118 is high performance, high efficiency 850 MHz 1 Watt GaAs Heterojunction Bipolar Transistor (HBT) power Amplifier with active bias. It is 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. It 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 Wireless data and digital applications. The SPA-2118 is a two-stage power amp featuring on-chip bias control for each stage.
