Product Description
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.
SXH-189
5-2000 MHz Medium Power
GaAsHBT Amplifier
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.
Its high linearity makes it an ideal choice for multi-carrier as
well as digital applications.
