0.18 μm GaAs-pHEMT MMIC Frequency Doubler for Radar Area Scanning Application

This paper proposes a GaAs-pHEMT MMIC frequency doubler for 60 GHz radar area scanning application using 0.18 μm GaAs technology. The aim of this study is to enter a frequency f0 = 30 GHz and to recover at the output a frequency of 2*f0, i.e. 60 GHz. The proposed multiplier is designed and optimized thanks to OMMIC library. The latter gives to the proposed frequency doubler added values in term of circuit performances. Indeed, it has low power consumption Pdc = 0.126 mW, high spectral purity and small size; it occupies an area of (1.35 × 0.63mm2) and achieves a conversion gain of −2.189 dB and an output power of 11.376 dBm. The results show a total efficiency of around 13.87%.
