Frequency Mixer Circuits: Applications and Topology Types
A frequency mixer that functions through switching uses a smaller input signal and passes it either inverted or non-inverted per the phase of the LO. Furthermore, operationally, this is the equivalent to a packaged double-balanced mixer, since the LO drive is significantly higher than the signal amplitude.

How to Multiply RF Signals without a Multiplier: The Switching Mixer
Well, first remember that mixing is multiplication. If you think of the LO as a square wave that transitions between 0 V and 1 V, the switch is effectively multiplying the input signal by the LO: When the switch is closed, the output is equal to the input multiplied by one. When the switch is open, the output is equal to the input multiplied by ...

Double Balanced Mixer Theory
Double Balanced Mixer. The double balanced mixer is a diode bridge mixer that uses two single-ended to differential transformers, or baluns, to create the multiplication of two input frequencies and cancel many of the unwanted harmonics and signals. Most notably is the cancelation (ideally) of the local oscillator and the input at several harmonics.
