In this letter, the bandwidth of the series of continuous modes (SCMs) power amplifiers (PAs) is extended. The SCMs are composed of a series of continuous working modes between Class-B/J and Class-F continuums. The second harmonic load of the series of continuums is purely reactive. By introducing resistive part to the purely reactive second harmonic load of the series of continuous modes, the operation bandwidth of power amplifiers is expanded. A broadband PA working across 0.8-3.05 GHz (117% bandwidth) is simulated and fabricated. Experimental results show that the drain efficiencies in interesting band are 57.4%-79%. The fabricated PA can deliver output power of 10.1-20.7 W.Index Terms-Broadband, high-efficiency, power amplifier, resistive-reactive, series of continuous modes.

In this letter, a series of inverse continuous modes for implementing highly efficient broadband power amplifiers (PAs) are proposed. These series of inverse continuous modes are extended from continuous Class-F −1 mode. A broadband PA, which operates across 2.4-3.9 GHz, is designed based on the series of inverse continuous modes (SICMs). The experimental results show that this power amplifier achieve drain efficiency of 62.2%-74.7% in the whole interesting band. The average output power of this designed PA is 11.9 W with average drain efficiency of 68.1%.Index Terms-Broadband, class-F −1 , high efficiency, power amplifier, series of inverse continuous modes.

“…However, the matching network, combined with the parasitics, can not keep the real part of fundamental impedance constant over a desired bandwidth. Therefore, other PA modes [5,6] based on Class-J or continuous Class-F are proposed to extend the design space of fundamental and second harmonics, and also the bandwidth.…”

In this paper, a C-band wideband power amplifier (PA) using a GaN HEMT is proposed. The general Class-J mode, which offer a bigger design space for the fundamental and harmonic terminations, is introduced to implement wideband PA. Then, to verify the mechanism mentioned above, a wideband PA operating from 3.5 to 6.0 GHz is proposed and fabricated. Meanwhile, the load/source harmonic and baseband impedances are also considered for the linearity. The amplifier exhibits 8-11 dB gain and 51%-64% drain efficiency (DE) covering from 3.5 to 5.5 GHz.
