| Description: | This paper proposes a novel design methodology combining class-E power amplifiers (PAs) with Sequential Load Modulated Balanced Amplifier (S-LMBA) architecture to enhance its bandwidth and efficiency. The proposed methodology aims to align the frequency-dependent optimal impedance trajectory of class-E PAs with the frequency-dependent optimal impedance trajectory of the S-LMBA's auxiliary stage, thereby expanding the achievable bandwidth of the S-LMBA architecture. The proposed methodology is validated on a PCB design using commercial GaN HEMT devices. The fabricated class-E S-LMBA achieves 41.9-43.4 dBm output power with 56-70% Drain efficiency (DE) at saturation and 34-49% of DE at 9-dB output power back-off (OBO) from 2.9 GHz to 4.2 GHz. |
