摘要：
This work demonstrates a complete Chireix system in which an analog signal component separator (SCS) is used to control the outphasing angle and amplitudes of the branch power amplifiers (PAs). The branch PAs are designed using load pull simulation as inverse class F amplifiers to obtain high efficiency. The branch PAs are directly connected to a signal combination network in one board to eliminate the phase error. The RF-input Chireix PA is demonstrated at 2.11GHz with peak output power 43.0 dBm and drain efficiency 73%.
