Product Description
Sirenza Microdevices鈥?SXA-3318B amplifier is a high efficiency GaAs
Heterojunction Bipolar Transistor (HBT) MMIC housed in a 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.
The matte tin finish on Sirenza鈥檚 lead-free package utilizes a post anneal-
ing process to mitigate tin whisker formation and is RoHS compliant per
EU Directive 2002/95. This package is also manufactured with green
molding compounds that contain no antimony trioxide nor halogenated fire
retardants.
