Abstract

A transistor modulator device for a frequency modulated oscillator characterized in that the modulator circuit comprises two transistors, advantageously supplied in parallel by a common voltage supply, whose bases and collectors are assembled respectively, and because the modulating signal, which attacks said bases through an appropriate circuit, it is applied by the emitters of said transistors to the main oscillating oscillator type oscillator circuit through at least two precision-adjusted weak value capacitors, the capacity between emitter-base electrodes being used as variable capacity. .
