Quadruple conversion superhet

In a Quadruple conversion superhet receiver, the radio frequency signal from the antenna input is converted several times, similar to the procedure in a double conversion superhet, but the additional frequency conversions are used for special features. For example, in the quadruple conversion superhets from Icom, the technology is used for realising the IF shift or passband tuning functions. In these sets, the IF filter curve can be shifted in relation to the reception frequency and thus an interfering signal can be faded out.

A high first intermediate frequency reduces the risk of mirror frequency reception.
