Product Description
Sirenza Microdevices’ SXB-4089 amplifier is a high efficiency InGaP/ GaAs
Heterojunction Bipolar Transistor (HBT) MMIC housed in low-cost, surface-
mountable plastic package.
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’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 manufactured with green
molding compounds that contain no antimony trioxide nor halogenated fire
retardants.
