The nonlinearity character of avalanche diode driven by external RF signals and its application to W band microstrip integrated high order multiplier

The analysis of nonlinearity character of avalanche diode driven by external RF signals are presented. The modulation effect of RF signals to avalanche diode give rise to the generation of high order harmonic currents. Then a microsrtip integrated high order multiplier based on avalanche diode is designed, fabricated and measured. Effective output power of 2.8mW and the phase noise of 90 dBc at 10KHz offset have been obtained at output frequency of 96GHz.
