Abstract:
1. A frequency converter, comprising: a frequency divider that divides an input signal frequency by a prescribed value to produce an output signal frequency; a frequency mixer that mixes the output signal frequency with a carrier signal frequency to produce a converted signal frequency, which is substantially equal to a difference between the output signal frequency and the carrier signal frequency, wherein the prescribed value and the input signal frequency are selected such that the carrier signal frequency is not substantially equivalent to an integer multiple of the output signal frequency; N frequency dividers that each divide the input signal frequency by prescribed values to produce N output signal frequencies, wherein N is an integer greater than one, and the sum of the N output signal frequencies is substantially equal to the carrier signal frequency; and an oscillator that generates the input signal frequency, wherein the frequency mixer is a single mixer that simultaneously combines the N output signal frequencies with the carrier signal frequency to convert the carrier signal frequency to a baseband signal frequency.
