Basic wiring / tutorial how to connect mixer to amplifier | Eduard Fahilan Falqueza

This simulation is of a Diode Mixer, commonly used in RF and communication systems for frequency conversion. It combines two input signals—an 8 MHz local oscillator (LO) and a 7 MHz radio frequency (RF) signal—using nonlinear components (diodes) to produce sum and difference frequencies (e.g., 1 MHz and 15 MHz). The waveform section shows the individual inputs and the mixed output, which contains these new frequency components. Such mixers are essential in superheterodyne receivers for downconve
