WebSimple outphasing systems have the efficiency characteristic of a linear class-B PA. Through proper selection of the shunt reactance, the efficiency of a Chireix outphasing system can be maximized at a specific output amplitude. The average efficiency with various amplitude-modulated signals is determined as a function of shunt reactance. WebFurthermore, a key advantage of the Chireix outphasing topology is the major flexibility in reconfiguring the OBO efficiency peak: in fact, the design of the two branch PAs can be carried out independently of the desired HEPR, since it is fully determined by the compensation susceptance. Finally, as in any outphasing architecture, the Chireix ...

WebAnother topology of dual-input Doherty-outphasing PA implemented with four transistors is proposed in [2], where the PA operates as a Doherty PA in the higher power region and a mixed-mode outphasing PA in the lower power region to provide a high average efficiency over an extended power backoff. In [3], a single-input Doherty-Chireix PA is ... WebChireix outphasing also benefits from discrete supply mod-ulation, as demonstrated by the multi-level Chireix outphas-ing (ML-CO) architecture [4], shown in Fig.1. In Chireix outphasing the amplitude modulation of the input signal is converted to additional differential phase modulation, which dates holiday on ice 2023
