W-band inductive high order frequency multiplier based on silicon avalanche diode

An investigation of millimeter wave high order frequency multiplier based on the 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. In experiment, the output power of 6.2 mW and 9.55 mW are obtained at output frequency of 94.05 GHz and 100.32 GHz with 15^th and 16^th multiplication order. The phase noise character is also according to the phase noise formula of frequency multiplier.
