Abstract
pHEMT-based switch circuits, devices including same, and methods of improving the linearity thereof. In one example, an antenna switch module includes a pHEMT switching circuit connected in series between an input signal terminal and a load terminal, the pHEMT switching circuit including at least one pHEMT configured to produce a first harmonic signal at the load terminal responsive to being driven by an input signal of a fundamental frequency received at the input signal terminal, the first harmonic signal having a first phase, and a gate resistance circuit connected to a gate of the at least one pHEMT and having a resistance value selected to produce a second harmonic signal at the load terminal, the second harmonic signal having a second phase opposite to the first phase.
