Which has the function of the circuit is called inverter (or mixers). The output signal frequency is equal to the sum of two input signal frequency, or for both other combination of the circuit. Mixer is usually composed of nonlinear components and frequency selective circuit. 【keywords】 mixer, frequency conversion, components 1
