- Design of a Bandpass Continuous Class‐F Filtering Power Amplifier Based on a Terminated Coupled Lines Structure Chenlu Wang Zhiwei Zhang Luyu Zhang Chao Gu Microwave and Optical Technology Letters ABSTRACTThis paper presents a filtered power amplifier (PA) based on the continuous class‐F mode. This broadband filtering PA employs a terminated coupled line structure, which consists of coupled line segments and four terminations loaded on them for obtaining high efficiency over a wide frequency band. Also, a detailed theoretical analysis and calculation of the proposed termination coupling line structure is given. The filter plays the role of filtering and impedance matching simultaneously, and thus high‐order harmonics of the filtering PA are suppressed. For verification, the proposed PA is designed, fabricated, and measured. The measurement results show that a drain efficiency of 60.5%–69.8%, a gain of more than 10 dB, and an output power of 40.2–42.4 dBm are achieved in the target frequency band. 10.1002/mop.70039 http://onlinelibrary.wiley.com/termsAndConditions#vor
