Universal Down Mixer Circuit Design for AM Broadcast Receiver Modification - This universal down mixer circuit diagram is designed in the case of AM-broadcast receiver modification to enable them as DRM-reception.

It operates from 455 KHz to 12KHz whilst the 12KHz output is supplied to the PC soundcard input where it is decoded using the software decoder.

This universal down mixer circuit works at 7-20V supply voltage range, less than 6mA current consumption, and the oscillator frequency of the chosen optional crystal oscillator is 443 KHz with 20x20x8,5mm board dimensions needed.
