SPA-2318

2150 MHz 1 Watt Power Amplifier with Active Bias

Stanford Microdevices 

Product Description

Stanford Microdevices’ SPA-2318 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.
