Stanford Microdevices鈥?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.
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.
