| Bandwidth and efficiency are two important indicators of power amplifiers design, how to make the power amplifier meet the
design requirements of wide bandwidth and high efficiency at the same time has been one of the hot spots and difficulties in the research
of amplifiers. For the problems mentioned above, this paper proposes a continuous class F ultra-wideband amplifier, based on hardware
intelligence and continuous power amplifier theory, expanding impedance matching space with continuous theory, which promote
traditional class F power amplifier to continuous class F power amplifier. And the scattered frequency bands are integrated into a whole
through reconfigurable technology, to broaden its working bandwidth effectively. By making the physical objects and testing, in the range
of 0. 9~ 4 GHz, the power added efficiency (PAE) is greater than 72%, the average gain is about 12. 5 dB, and the saturated output
power is 41 dBm. This paper combines the advantages of both reconfigurable technology and continuum theory. The designed power
amplifier has high efficiency, wide operating band, and circuit flexibility, which can adapt well to the requirements of 5G wireless
communication system. |
