Nonlinear RF Characterization and Modeling of Heterojunction Bipolar Transistors Under Pulsed Conditions

Abstract

I(V) and S-parameters pulsed measurments have been performed on a heterojunction bipolar transistor for currents up to 105 Amps/cm2. S-parameters data have been acquired in the whole device output domain. So, a nonlinear DC to RF consistent model has been obtained with I(V) and RF pulsed measurements on a GaInP/GaAs HBT transistor, processed by the central research laboratory of Thomson CSF.
