Abstract

A novel design of frequency multiplier using a feedforward technique and a defected ground structure (DGS) is proposed. The feedforward loop in the proposed frequency multiplier suppresses the fundamental component (f0) the dumb-bell or spiral shaped DGS diminish unwanted harmonics such as second, third, fourth. Due to the combination of the feedforward structure and the DGS, only the multiplied frequency component (2f0, 3f0, 4f0 ) appears at the output port and the other unwanted components are suppressed excellently. The frequency multipliers are designed at 1 GHz of f0, by the proposed technique and measured. The measured output power of2f0, 3f0, 4f0 is -2.59 dBm, -5.36 dBm, -4.57 dBm, respectively, when the input power is 0 dBm
