Double balanced mixer circuit. In addition to the improved isolation provided a double balanced mixer also produces very low levels of spurious signal and therefore the overall receiver will have low levels of spurious responses. This is a key element of any design ensuring that spurious signals and strong signal performance are optimised

Description. Here is a simple 3 input mic mixer circuit using the popular uA 741 ICs. Four 741s are used here.IC1 IC2 IC3 are used as preamplifiers. They produce a gain of around 40 decibel to the individual input signals. The IC4 is wired as a summing amplifier to add the signals from three preamplifiers.IC4 also gives a gain of around 5decibel to the final output signal. Total gain of the
