====== 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|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.
