MK484 Datasheet Document The MK484 is a monolithic integrated circuit designed in a TO92 package for use as a one chip radio solution, high sensitivity and high quality AM radio is possible with very few external components. Special features of the circuit include low supply voltage operation, the Device is particularly suited to small hand-held… Read More »
This two chips AM radio receiver circuit is a tuned radio frequency (TRF) receiver of the standard AM (amplitude modulation) radio with broadcast frequencies at 550kHz-600kHz. This is a simple and easy to build AM radio circuit which only using two integrated circuits (IC). This circuit works with 9V voltage supply, you could use 9V… Read More »
