The Research of W-Band High Order Frequency Multiplier Based on Avalanche Diode

Abstract

Abstract-A research of millimeter wave high order frequency multiplier based on the fierce inductive nonlinearity of avalanche diode is presented. The operation of high order frequency multiplication is introduced, and the high order harmonics generation character under external RF field modulation is analyzed. The characteristic of multiplier circuit is also discussed. Maximum output power of 6 mW and minimum conversion loss of 17 dB are obtained at output frequencies of 94 GHz and 96 GHz with 15th multiplication order. The phase noise of output 94 GHz signal is about −90 dBc/Hz and −94.33 dBc/Hz at 10 kHz and 100 kHz offset.
