Abstract This paper presents a compact, single-path-footprint Doherty PA with minimized passive network areas. A systematic analysis for its realization is developed based on the proposed theory of reciprocal Doherty networks employing a single transformer. Implemented with only three transformer footprints and a single driver, the design occupies a core area of 0.12mm2, comparable to that of a linear PA, while supporting wideband, high-order QAM OFDM signals with high average efficiency. Beamforming phased arrays have become indispensable for wireless communication and sensing at upper mid-band and millimeter-wave (mm-wave) spectra, where they provide access to abundant bandwidth while compensating for severe path loss. By integrating multiple RF chains, phased-array transceivers enable highly directional communication that improves link quality, while the adoption of dual polarization further doubles the number of
