SBA4086Z
DCto5GHz, CASCADABLE InGaP/GaAs HBT
MMIC AMPLIFIER
Package: SOT-86
Product Description
Features
RFMD’s SBA4086Z is a high performance InGaP/GaAs Heterojunction
Bipolar Transistor MMIC Amplifier. A Darlington configuration designed
with InGaP process technology provides broadband performance up to
5GHz with excellent thermal performance. The heterojunction increases
breakdown voltage and minimizes leakage current between junctions.
Cancellation of emitter junction non-linearities results in higher suppres-
sion of intermodulation products. Only a single positive supply voltage, DC-
blocking capacitors, a bias resistor, and an optional RF choke are required
