Product Description
Sirenza Microdevices’ SBF-4089 is a high performance InGaP/
GaAs Heterojunction Bipolar Transistor MMIC Amplifier. A
Darlington configuration designed with InGaP process
technology provides broadband performance up to 0.5 GHz
with excellent thermal perfomance. The heterojunction
increases breakdown voltage and minimizes leakage current
between junctions. Cancellation of emitter junction non-
linearities results in higher suppression of intermodulation
products. Only a single positive supply voltage, DC-blocking
capacitors, a bias resistor, and an optional RF choke are
required for operation.
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.
