N2 - In this work, a V-band monolithic frequency quadrupler with an effective rejection of undesired harmonic signals and a large dynamic range based on 0.15 μm GaAs PHEMT process is presented. The quadrupler structure is formed by cascading a single-stage inputdriver amplifier, anactive quadrupling section, a BPF and a 3-stage output power amplifier in V-band. The single-stage input power amplifier is designed to provide suitable input power for the quadrupler required for minimum conversion loss. The size of the MMIC is 2.5 × 2.2 mm2. As per measurement results, with 0 dBm input signal in the frequency range of 12.0-12.5 GHz, the conversion gain of the MMIC quadrupler is observed slightly greater than 10 dB. Within the given frequency band, the minimum suppression of fundamental signal is 50 dBc, and minimum relative rejections for second, third and fifth harmonic signalsare 48 dBc, 57 dBc, and 44 dBc respectively. Input and output ports are matched to 50 and return lossesare better than 10 dB. The total current is around 62 mA at 3 V DC bias.
