demand for multi-Gb/s data-rates has accelerated the rapid development and standardization of the 5G technology, particularly in the mm-wave bands [1-11]. With 5G, there is a significant anticipation for the widespread utilization of high-speed and spectrally efficient modulation schemes. As a result, the importance of both modulation efficiency and high average output power (Pout) of power amplifiers (PAs) is increasing. This becomes especially crucial in User-Equipment (UE) devices, whose compact form factor imposes constraints on the integration of antenna-array elements. Furthermore, the advancement towards low-cost and multifunctional architectures [1-3] necessitates future mm-wave front-ends to enable multiband and
