The power added efficiency (PAE) and the linearity of the Doherty amplifier has been improved using the dual bias control and the photonic band gap (PBG) structure. The PBG structure has been used to implement on output matching circuit and the dual bias control has applied to improve the PAE of the Doherty amplifier at a low input level by applying it to a carrier amplifier. The Doherty amplifier...
This paper has presented a novel envelope elimination and restoration (EER) structure using class-F power amplifier. The photonic bandgap (PBG) structure has been applied to suppress the 2nd and 3rd harmonics on output matching network. The envelope tracking circuit of EER structure has consisted of the envelope detector and the DC-DC converter. The power added efficiency (PAE) and the 3rd order inter-modulation...
