This work presents the design and experimental characterization of a wideband continuous inverse class-F power amplifier, covering several bands in the 5G FR1 frequency range, and thus suitable for base station applications. The design spaces of the class-F and inverse class-F in terms of input and output terminations are reviewed and compared, and the design choices relative to an implementation using a packaged device are described. Measurements show a saturated output power of 40 dBm, with corresponding efficiency and gain higher than 70% and 13 dB, respectively, over 1.4-2 GHz. The performance is well in line with the state of the art and is accurately predicted by simulations, proving the effectiveness of the design strategy.

Abstract
This work presents the design and experimental characterization of a wideband continuous inverse class-F power amplifier, covering several bands in the 5G FR1 frequency range, and thus suitable for base station applications. The design spaces of the class-F and inverse class-F in terms of input and output terminations are reviewed and compared, and the design choices relative to an implementation using a packaged device are described. Measurements show a saturated output power of 40 dBm, with corresponding efficiency and gain higher than 70% and 13 dB, respectively, over 1.4-2 GHz. The performance is well in line with the state of the art and is accurately predicted by simulations, proving the effectiveness of the design strategy.File | Dimensione | Formato | |
