Title: Dielectric oscillator
Inventor: NISHIDA HARUKI
IPC: H03B9/14
Filed: 1986-09-10
Abstract: PURPOSE:To oscillate a dielectric oscillator in a wide frequency range by arranging a dielectric chip so as to be moved simultaneously and oppositely with/to a transmission line and changing the resonance frequency of a dielectric resonator and the effective electric length of the transmission line. CONSTITUTION:When the dielectric chip 4 is separated from both resonator 1 and the transmission line 1 due to the rotation of a screw 6 and the opposed distance between the chip 4 and both units 1, 2 is increased, magnetic field coupling is weakened, the effective dielectric constant of a medium is reduced and the resonance frequency of the resonator 1 is changed upward. Since the effective electric length of a coupling line 21 of the transmission line 2 is also shortened simultaneously with said change though the mechanical length is the same, the coupling length lambdag/4 of the line 21 with the resonator 1 and the optimum length of an oscillation phase of a transistor 3 can be maintained. When the opposed distance is reduced due to the rotation of the screw 6, the magnetic field coupling is strengthened, the effective dielectric constant of the medium is increased and the resonance frequency of the resonator 1 is changed downward. Since the effective electric length is increased simultaneously with said change, the optimum length of the oscillation phase is also maintained simultaneously with said case. Thus, the dielectric oscillator with a wide band can be easily constituted based on simple construction.
