Abstract This paper presents an ultra-compact asymmetrically load-pulled series Doherty PA in 22nm CMOS SOI with a single-footprint output combiner. A quantitative analysis of a single transformer as an impedance inverter enables a passive-network transformation to a single- footprint EM structure. In addition, an asymmetric load-pull concept is proposed. The PA achieves 25.3dBm Psat, 1.56W/mm2 power density, up to 30% PAE6dB, and wideband modulation for 3GHz QPSK and 2GHz 64QAM. As 6G continues to redefine the limits of wireless communication, the Frequency Range 3 (FR3) spectrum (7 to 20GHz) is emerging as a leading candidate, with the 10-to-15GHz Ku band offering a more favorable trade-off between coverage and capacity than the existing mm-wave FR2 solutions. While FR2 deployments have struggled due to high installation costs, severe path loss, and limited coverage, the commercial success of Ku-band satellitecommunication (SATCOM) constellations like Starlink highlights FR3 practi
