SXA-389
Product Description
Sirenza Microdevices’ SXA-389 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.
SXA-389
SXA-389Z Pb RoHS Compliant
& Green Package
400-2500 MHz ¼ W Medium Power
GaAs HBT Amplifier with Active Bias
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.
The matte tin finish on Sirenza’s lead-free package utilizes a post
annealing process to mitigate tin whisker formation and is RoHS
compliant per EU Directive 2002/95. This package is also manu-
factured with green molding compounds that contain no antimony
trioxide nor halogenated fire retardants.
