A novel W-band microstrip integrated avalanche diode high order frequency multiplier

摘要

A W band microstrip integrated high order frequency multiplier based on avalanche diode is proposed. The property of avalanche high order multiplication mode is analyzed based on physical operation mechanism of avalanche diode. According to the harmonics impedance model of avalanche diode, the microstrip integrated multiplier is designed, fabricated and measured. Output power of 5.78 mW has been obtained at output frequency of 94.5 GHz with 15th multiplication order and the phase noise is -90 dBc/Hz and -95 dBc/Hz at 10 KHz and 100 KHz offset. Good results at 13th and 17th multiplication order are also obtained.
