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
