Patent ID: 8275263

Claim:
A phase deviation multiplication apparatus, comprising: a plurality of sequentially arranged phase deviation multipliers comprising at least a first phase deviation multiplier and a last phase deviation multiplier, each of the plurality of phase deviation multipliers being responsive to an input signal and a pump signal to generate a respective plurality of frequency combs, each of the frequency combs having a respective phase deviation multiplication factor relative to the phase deviation of the input signal of the respective phase deviation multiplier, each of the plurality of phase deviation multipliers providing a selected phase deviated signal bypassing a selected frequency comb, the selected frequency comb providing a predetermined phase deviation multiplication factor, at least one phase deviation multiplier prior to the last phase deviation multiplier filtering out at least one of its input signal or its pump signal; wherein the first phase deviation multiplier is configured to receive an input signal and the last phase deviation multiplier is configured to generate a last phase deviated signal, and wherein the last phase deviated signal has a phase deviation multiplication factor that is the product of the respective predetermined phase deviation multiplication factors of the plurality of phase deviation multipliers.
