(TU Delft Electronics) Pashaeifar, M. (TU Delft Electronics) D'Avino, Marco (Catena) de Vreede, L.C.N. (TU Delft Electronics) Alavi, S.M. (TU Delft Electronics) Date 2021 Abstract Continuous Class F (CCF) power amplifiers (PAs) overcome Class-F PA's disadvantage of narrow bandwidth by relaxing the short-circuit requirement at the 2nd harmonic while still maintaining 90.7% peak efficiency over the band of interest. This paper proposes four different CCF output networks, with their design procedure, suitable for on-chip implementation in the 2.1-2.7GHz band. The output stage with 2nd harmonic trap and no RF choke is favoured due to its flat real impedance, low fundamental reactance, and compact layout. Using a 40nm CMOS process, a passive efficiency of 68% at 2.4GHz for this structure is in reach.
