Abstract : In the homodyne multiplier, a frequency mixer has both the radio frequency and local oscillator input ports driven by the same signal source, generating multiples of the input frequency as output signals. The signals coupled to the respective input ports of the mixer are controllable in phase and amplitude with respect to each other. The output of the mixer then generates a large number of signals which have a high degree of phase coherence with the original driving signal. Since the mixer functions as a non-linear combination element, phase perturbations are not internally generated which adversely affect coherence. Attenuators in the transmission lines to the mixer inputs allow adjustment of signal levels.
