| contents | Design of Broadband Doherty Power Amplifier Based on Spoof Surface Plasmon Polaritons Hongbo Zhang Maojia Geng Giovanni Crupi Jialin Cai International Journal of Circuit Theory and Applications ABSTRACTSpoof surface plasmon polariton (SSPP) is a technique for controlling and manipulating electromagnetic waves within the microwave frequency range through ultrathin corrugated metallic strips. According to current research, SSPPs are primarily used for designing passive circuits and single‐ended power amplifiers (PAs). This work employs SSPP theory for the design of a broadband high‐efficiency Doherty power amplifier (DPA). The input and output matching networks of the carrier power amplifier (CPA) and peak power amplifier (PPA) are designed based on SSPP structure in order to improve the back‐off (BO) efficiency of the DPAs. Results of measurements indicate that the proposed height‐variable SSPP‐based DPA achieves a saturated output power of 41.4 dBm and a maximum efficiency of 61.1% within the frequency range of 1.6–2.2 GHz, whereas BO efficiency remains above 51.2%, demonstrating the effectiveness of the proposed techniques. 10.1002/cta.4439 http://onlinelibrary.wiley.com/termsAndConditions#vor |
