The next generation mobile communication systems impose challenging performance, size and cost requirements on the power amplifiers. This paper presents novel DC-biasing circuits, which are compact and yet can control the harmonics almost arbitrarily, thereby allowing to save the space for additional harmonic tuning circuit. The proposed circuit consists of a composite right-/left-handed (CRLH) transmission line (TL) stub, of which the size and harmonic-control function can be tuned by modifying the dispersion diagram of the stub line. As a proof of concept, a compact 2-GHz 5-W GaN HEMT class-F PA using the versatile CRLH-TL stubs was fabricated, demonstrating 85% drain efficiency and 76% Dower-added efficiency.
