Abstract :
In this work we introduce a novel technique for modelling the distributed amplifier (DA) and in particular, the heterojunction bipolar transistor (HBT) based DA. This modelling accounts for all feedback and parasitic elements associated with the HBT. Microwave simulations of a distributed amplifier based on our model are contrasted to those obtained from existing models and show significant improvement
