Product Description
Sirenza Microdevices’ SBA-4086 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.
