am radio receiver with mk484

Posted on Feb 5, 2014

Here is a schematic of a good quality AM radio receiver circuit. The heart of the circuit is MK484 AM radio IC. It is a high sensitivity and high quality IC, it has only three leads and comes in TO92 package and require only few external parts because all the necessary circuitry like RF amplifier, AGC and detector are incorporated inside the IC.

he circuit can be operate only on 1. 5V DC and has a very low current consumption only 0. 3mA so the 1. 5 volt battery will last more then hundred hours. Do not give more then 1. 8 volt to the IC. The Coil L1 is equal to 55 turns of 0. 315mm (30 swg) enamelled copper wire wound on 10mm x 100mm long ferrite rod.
