Product Description
Sirenza Microdevices鈥?SXA-389B 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 400-2500 MHz cellular, ISM, WLL, PCS, W-
CDMA applications.
Its high linearity makes it an ideal choice for multi-carrier as well as digital
applications.
