Abstract
A new method for the determination of the four noise parameters of an InP double heterojunction bipolar transistor (DHBT) based on a 50-Ω noise measurement system without a microwave tuner is presented. The noise parameters are determined based on the noise correlation matrix technique by fitting the measured noise figure of the active device. On-wafer experimental verification up to 20 GHz is presented and a comparison with a tuner based method is given. Good agreement is obtained between measured and calculated results up to 20 GHz for the InP/InGaAs DHBT with a 1.6 × 20 μm2 emitter over a wide range of bias points.
