Loadline Design

Loadline Design The output of a power amplifier (PA) is terminated with a specific impedance. This impedance is required for optimal linearity or power generation or efficiency or combination of such specs, and is determined by loadpull analysis. We call it loadline. While a loadline helps PA deliver its performance, the matching (VSWR) gets ruined […]

RFIC Transformer Model

RFIC transformer turn ratio

Integrated Transformer Models We decided to write this article because there are only so many different models of a transformer that exist. Analog IC designers, RFIC designers and mm-wave IC designers – they all understand transformers a little differently. Enough is enough. We are putting together a list of different models (with derivations of course) […]
