This is a schematic for radio receiver circuit. This circuit is based on the TDA7088T that can be used in mono portable and pocket radios. This is a bipolar integrated circuit. This is the figure of the circuit;
When a minimum of peripheral components (of small dimensions and low cost) is important, we can use TDA7088T. Frequency-locked -loop (FLL) system with an Intermediate Frequency (IF) of about 70 KHz is built on this circuit. By active RC-filters, selectivity is achieved. De-tuning related to the IF and the mute circuit is suppress too week input signals. [Schematic circuit source: NXP Semiconductor Application Notes]
