Very-high-rank avalanche diode frequency multiplier

Recent experimental observations on silicon avalanche diode multipliers operated at about 35-GHz output frequency are presented. High-rank (up to 35) frequency multiplication is achieved with output power over 250 mW and conversion loss of 13 dB. The possibility of frequency multiplication by any integer n ranging from 8 to 35 with the same diode and without any idler circuit is pointed out. It is concluded that any output frequency can be selected between 28 and 39 GHz by varying the input frequency and the circuit tuning.
