WebDec 5, 2024 · A Chireix outphasing PA is designed using two 15-W GaN HEMTs. A Chireix outphasing PA exhibits a peak efficiency of 72.58% with peak power of 43.97 dBm and a 8-dB backoff efficiency of 75.22% at 1.9 GHz. Measurements with 10-MHz LTE signals with 9.6-dB PAPR yield 59.4% average drain efficiency at 1.9 GHz while … 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
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 ... WebSep 1, 2024 · Nonlinearity modeling of a Chireix outphasing power amplifier.
