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.
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.
