Unlike a normal mixer, there is a fairly clear optimum drive level, above which the conversion loss increases. A harmonic mixer can be used to avoid the complexity of generating a microwave local oscillator, and is common as a simple and reliable frequency extender to a low frequency design. [3] [4]
Frequency mixer symbol. In electronics, a mixer, or frequency mixer, is an electrical circuit that creates new frequencies from two signals applied to it.In its most common application, two signals are applied to a mixer, and it produces new signals at the sum and difference of the original frequencies.
Harmonic mixing or key mixing (also referred to as mixing in key) is a DJ's continuous mix between two pre-recorded tracks that are most often either in the same key, or their keys are relative or in a subdominant or dominant relationship with one another. The primary goal of harmonic mixing is to create a smooth transition between songs.

A direct-conversion receiver (DCR), also known as homodyne, synchrodyne, or zero-IF receiver, is a radio receiver design that demodulates the incoming radio signal using synchronous detection driven by a local oscillator whose frequency is identical to, or very close to the carrier frequency of the intended signal.
The harmonic mixer turns the reference signal into an impulse train that is rich in harmonics. [ b ] The VCO output is coarse tuned to be close to one of those harmonics. Consequently, the desired harmonic mixer output (representing the difference between the N harmonic and the VCO output) falls within the loop filter passband.
A simple mixer will pass both of the input frequencies and all of their harmonics along with the sum and difference frequencies. If the simple mixer is replaced with a balanced mixer then the number of possible products is reduced. If the frequency mixer has fewer outputs the task of making sure that the final output is clean will be simpler.
