Abstract

FIELD: radio engineering. SUBSTANCE: superheterodyne receiver input circuit has first, second, third, and fourth inductance coils 1-4, first, second, and third pairs of varicaps 5-7, first, second, and third resistors 8-10 adjustable D.C. voltage supply 11, first and second capacitors 12,13. Receiver circuit is arranged so that decoupling between input band filter and heterodyne circuit is provided upon arrival of signal and voltage from heterodyne while all varicap pairs are supplied with equal heterodyne voltage. This will greatly reduce control D.C. voltage across varicaps without occurrence of stray detuning of band filter and heterodyne circuit. EFFECT: simplified design. 2 dwg
