Mixer Schematic. Of course there are many other circuits for the same purpose. The full output of the mixer circuit is vout rf v1 r1 v2 r2 v3 r3.
It is typically used when an rf mixer module is used. The mic inputs are suitable for low impedance 200 1000r dynamic microphones. This circuit symbol indicates the multiplication aspect of the mixer.
If we had two signals to be mixed.
The key rf mixer circuit symbol shows the two signals entering circuit block consisting of a circle with a cross or x within it. Audio schematics mixer circuits. 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. Set the ac voltage amplification factor through the ration of r2 r1.
