A transistor grid oscillator tunable by the voltage and incorporated grid has a wide band comprising such oscillators

摘要

The oscillator comprises a support plate by a dielectric material 15 comprising a first face, metallic at least in part in order to form the ground circuit 16 defining the reference potentials of the oscillator and possessing a second face parallel to the first face on which are disposed the components of the oscillator, a resonator and a transistor 4 mounted in common collector and the torque by its base to the resonator in order to allow the maintenance of oscillations. The sender, is connected by two capacitors 13, 14 to the ground potential. Each capacitor 13, 14 is formed by a first metallic plate 17, 18 filed on the second face of the support plate, a second metallic plate formed by the first face 16 of the support plate metallic. The electrode of the collector of transistor is connected to the part metallic 16 of the first face by a hole metallise 19 connecting the first face to the second face. / p & & p & application: synthesizers of frequency.
