Abstract(in English) | In this paper, we present a broad-band and high-efficiency C-band internally-matched FET. Optimum impedances at fundamental and second harmonic frequencies were accurately estimated from source- and load-pull simulation by using an accurate large signal FET model. The matching circuits were designed to realize the optimum impedances in a broad-band. The large signal FET model is based on Angelov model, which accurately predicts I-V characteristics of FETs. The model parameters were extracted for a unit cell FET with a small gate width. We scaled up the unit cell FET model to 1 chip FET model with a wide gate width, accounting for increase of source inductance by sharing via holes. The developed internally-matched FET has achieved power-added efficiency (PAE) of over 65 % across 300MHz bandwidth. It is confirmed that internally-matched FETs can be effectively designed by using the large signal FET model. |
