SummaryWe propose a broadband high‐efficiency power amplifier (PA) with output power between 42.6 and 44.7 dBm, drain efficiency (DE) over 62%, and power additional efficiency (PAE) over 52% in the 2.3–3.5GHz frequency band. This PA effectively combines the high‐efficiency characteristics of class‐F PAs with the advantages of controlling the second harmonic for obtaining high efficiency at large bandwidth. The Dual Band Harmonic Control and Matching Network (DBHCN) realizes the conversion from 50 Ω to high‐efficiency impedance space (HEIS) while controlling the high‐order harmonics in different frequency bands. The proposed PA can be used for the fifth‐generation mobile communication technology (5G) base stations and broadband radars.

This letter presents a novel dual-band tunable bandnotched antenna. The antenna consists of a monopole ultrawideband (UWB) antenna and two kinds of novel notched structures. A tunable notched wave is obtained by adjusting the capacitance on the notched structure. Monopole antenna works well on 3.1-10.6 GHz. The low frequency notched wave can be adjusted on the 3-4 GHz, and the high frequency band notched wave can be adjusted on the 5-6 GHz, which can avoid the influence of the WiMax and WLAN narrowband communication system on the UWB communication system, and improve the performance of the antenna system. At the same time, through the analysis of the surface current distribution of the notched antenna, the principle of the notched wave is studied. At last, a prototype of the band-notched antenna is fabricated and measured whose simulation is consistent with the measurement.
