Product Description
Sirenza Microdevices’ SBA-5089 is a high performance InGaP/
GaAs Heterojunction Bipolar Transistor MMIC Amplifier. A
Darlington 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.
