Abstract :
In this paper, we propose a high power and wideband dual-fed GaN HEMT DP A for 2.6 GHz WiMAX applications, which is implemented a push-pull GaN HEMT with the P1dB of 20 W to avoid circuit complexity and large size. From the measured results for a continuous wave (CW) and a WiMAX signal, the dual-fed GaN HEMT DPA shows wideband performances.
