SBA-4089Z
DC-5 GHz, Cascadable
InGaP/GaAs HBT MMICAmplifier
Sirenza Microdevices’ SBA-4089 is a high performance InGaP/
GaAs Heterojunction Bipolar Transistor MMICAmplifier. ADarlington
configuration designed with InGaP process technology provides
broadband performance up to 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 manu-
factured with green molding compounds that contain no anti-
mony trioxide nor halogenated fire retardants.
