A three-section transmission-line transformer for matching three arbitrary frequencies and an arbitrary load is proposed. In this paper, the design parameters of the proposed transmission line are analyzed based on an ideal transmission-line circuit model. A design procedure and some simple design equations are derived. The validity of the results is proven(More)
This paper presents a compact size frequency doubler using an artificial transmission line design approach. The multiplier features conversion gain and high fundamental signal rejection. The frequency multiplying is employing the current combining push-push technique. Two GaAs FETs are driven by 900 MHz anti-phase signals from a simple LHM-TL phase shifter(More)
