Frequency divider for signals in gigahertz (GHZ) range, with mixer of input signal with feedback output signal, containing bandpass characteristic of mixer amplifying (MOS) transistors for working frequencies of several 10 GHz

摘要

Frequency divider with frequency mixer (1) for input signal (a) with output signal (b) fed back from output (4) of frequency divider. At least one inductivity (L1,2) is linked to output as load. Inductivities are so designed that they form, with capacities of mixer, resonance circuit.Resonance circuit comprises frequency, corresponding to half frequency of input signal, containing maximum impedance. Preferably one capacity is formed by parasitic capacity of frequency mixer, which may contain push-pull mixer (T1-6).
