Super heterodyne receivers

Amplification at the IF and detection of the audio signal is handled by the MK484 (originally produced as the ZN414Z by GEC Plessey). This IC contains a 10 transistor TRF receiver circuit packaged in a three-pin TO-92 package. The MK484 implements a TRF receiver by cascading three high-gain RF amplifiers followed by a transistor detector.
