摘要

Improvements in tuner circuits of frequency modulated in radio receivers to transistors, characterized in that the radioelectric signals picked up by an adjustable telescopic antenna and present in the input transformer are tuned in the secondary of this one by means of a capacitor, of variable capacity or not, and they are applied to the emitter of the first high frequency amplifier transistor, obtaining a resonance in the upper part of the frequency modulation band and a relatively low Q quality coefficient, with a uniform and wide bandpass.
