RF mixers or frequency mixers as they are often called, are one of the main building blocks for RF circuit design. Frequency translation is a major capability, used in a host of different applications, and it is a key element of radio communications equipment technology: both for …

Subject: Re: [LTspice] Audio Frequency Mixer Hello everyone, Has anyone designed Audio frequency mixers? When I say mixer, I mean a circuit that can beat two frequencies (like in the RF range) to get sums and differences to translate audio signals to higher ranges. I have found some multiplier ICs but i am not too happy with the voltage ranges they

An ideal mixer is usually drawn with a multiplier symbol A real mixer cannot be driven by arbitrary inputs. Instead one port, the “LO” port, is driven by an local oscillator with a fixed amplitude sinusoid. In a down-conversionmixer, the other input port is driven by the “RF” signal, and the output is at a lower IF intermediate frequency

It's a filter that cuts off any frequencies above a particular point. Simply put, when you use this filter in your audio mixing, you can cut off certain frequencies and avoid them from having in your final audio file. The way this filter works is pretty straightforward.

A mixer takes an RF input signal at a frequency fRF, mixes it with a LO signal at a frequency fLO, and produces an IF output signal that consists of the sum and difference frequencies, fRF ± fLO. The user provides a bandpass filter that follows the mixer and selects the sum (fRF + fLO) or difference (fRF – fLO) frequency.
