SBA4089Z

DCto5GHz, CASCADABLE InGaP/GaAs HBT

MMIC AMPLIFIER

RFMD’s SBA4089Z is a high performance InGaP/GaAs Heterojunction Bipolar Tran-

sistor MMIC Amplifier. A Darlington configuration designed with InGaP process tech-

nology provides broadband performance up to 5GHz with excellent thermal

performance. The heterojunction increases breakdown voltage and minimizes leak-

age 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.
