“…To reduce the overall energy consumption of a system significantly and maintain the high-efficiency of the PAs, many PA configurations have been introduced to improve the efficiency of the PAs. Such as switch-mode PAs (SMPAs) [6][7][8][9][10][11][12][13][14] or harmonically tuned topologies [15][16][17][18][19]. Among them, SMPAs are considered the most promising candidate due to their 100% theoretical efficiency and relatively concise topology.…”

This paper presents a design method for a watt-level high-efficiency broadband power amplifier (BPA) with a generalized parallel-circuit (PC) Class-E model. A combination of the singlereactance compensation technique (S-RCT) and Chebyshev low-pass (LP) impedance matching network (MN) is used for achieving PA's broadband characteristics. The analytical expression of the operation and power loss mechanisms of PC Class-E PA, which includes the effects of a finite DC-feed inductance, transistor on-resistance, and a broadband MN, is elaborated. As an example, a highly-efficient broadband PC (BPC) Class-E PA operating at 12 V drain supply voltage is implemented and verified experimentally. The designed PA exhibits high-efficiency characteristics of 82.15%-86.3% drain efficiency (DE) and 36.92-38.57 dBm output power (Pout) with 19.95-23.11 dB power gain in the band from 7 MHz to 9.4 MHz. The measured results show good agreement with the theoretical and simulated results. INDEX TERMSClass-E, parallel-circuit, power losses, high-efficiency, broadband matching, power amplifier.

“…By far several techniques have been implemented by researchers and using switch‐mode topologies Class‐E, and Class‐F, and inverse Class‐F most of the high‐efficiency PAs are designed 3‐10 . In Reference 3 a broadband Class‐ E M PA has been proposed using the double reactance compensation technique by adding a parallel resonator within the main circuit load network.…”

In this work, a 0.9–2.4 GHz, 25 W output power, radio frequency (RF) power amplifier based on Class‐E switchmode topology has been analyzed. A load‐pull simulation method is used to optimize the power performance in the operating band. To design input and output matching networks an optimized low pass filter network was used. Simulated results of the power amplifier (PA) demonstrate wideband behavior which covers a 0.9–2.4 GHz band with an efficiency of 25%–78%, an output power of 25 W (44 dBm), and an average gain of 17 dB. The designed PA provides attractive features associated with a wider band, high gain, and efficiency, which makes it a proper candidate for the mobile transmitter and cellular infrastructure applications.
