“…Although some valuable advances have been obtained in existing research [7][8][9][10][11], the design of broadband PAs is often constrained by drastic changes in impedance values and misfits between fixed matching networks [12]. In this paper, we design a broadband PA, using filter matching networks with large impedance variation space.…”

This paper presents a new realization method of a broadband power amplifier based on a novel filter matching network. The novel matching network based on band-pass filter has an excellent frequency-selection function, which can ensure the novel matching network has excellent characteristics in the aim band and generates the out-of-band harmonic suppression. Finally, we manufactured the power amplifier and measured it. The saturated output power is greater than 40 dBm in the range of 1 to 3 GHz, limited to ±1.5 dB of the gain flatness, and the rejection of harmonic is stronger than −20 dBc.
