Preliminary
Product Description
SPA-2318
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.
2150 MHz 1 Watt Power Amplifier
with Active Bias
This product is specifically designed for use as a driver
amplifier for infrastructure equipment in the 2150 MHz PCS
band. Its high linearity makes it an ideal choice for multi-carrier
and digital applications.
