| Popis: | A broadband S-band high efficiency internally matched 240 W GaN high power amplifier (HPA) has been developed. To obtain wider operating bandwidth and higher efficiency HPA, an output matching network with shunt inductors and 2nd harmonic reflection open-stubs connected by transmission lines is employed. To verify this methodology, we fabricated an S-band HPA and the output power of 240 W and the power added efficiency of 54.4 % over from 2.6 to 3.4 GHz were achieved. To the authors' knowledge, this is one of the widest bandwidth performances among the ever-reported S-band GaN HPAs over 100 W output power. |
