Product Description
SXH-189
5-2000 MHz Medium Power
GaAsHBT Amplifier
Stanford Microdevices’ SXH-189 amplifier is a high efficiency
GaAs Heterojunction Bipolar Transistor (HBT) MMICs housed
in low-cost surface-mountable plastic package. These HBT
MMICs are fabricated using molecular beam epitaxial growth
technology which produces reliable and consistent
performance from wafer to wafer and lot to lot.
These amplifiers are specially designed for use as driver
devices for infrastructure equipment in the 5-2000 MHz cellular,
ISM, WLL and narrowband PCS applications.
Product Features
