SXT-289 Datasheet, PDF (1/8 Pages) Stanford Microdevices – 1800-2500 MHz Power Amplifier

Product Description
Stanford Microdevices’ SXT-289 amplifier is a high efficiency
GaAs Heterojunction Bipolar Transistor (HBT) MMIC 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 1800-2500 MHz
cellular, ISM, WLL and Wideband CDMA applications.
Its high linearity makes it an ideal choice for multi-carrier as
well as digital applications.
