Dielectric resonator device using coupled microstrip line

摘要

1. The art that the invention defined in the claims ; the present invention. The thing of the dielectric resonator using a transmission line in combination ; 2. SUMMARY OF THE INVENTION The attempt to resolve ; The present invention improves the quality factor of the resonance signal of the low-voltage control voltage input by using a magnetic coupling to strong coupling of the dielectric resonator coupled transmission line portion, using him and for preventing the phase noise and spurious noise is generated in the oscillation signal output from the voltage-controlled oscillator, to provide a dielectric resonator using a transmission line by combining its purpose is that. ; 3. Solution subject matter of the invention ; This invention provides a dielectric resonator using a transmission line in combination, the counter having a different width to prevent the decrease in the quality factor resonance signal by using a magnetic coupling jidoe comprises a first and a second coupling transmission lines, one end portion coupled to the transmission line connected to the input end of the oscillation element of the transmission line to the second coupling; Dielectric resonance element for resonance signals of a specific frequency through the interlocking of the coupling to the second transmission line is located on the side of the transmission line to the second coupling; Resonance frequency varying means for varying the resonance frequency is connected to the other end of the transmission line coupled to the first, by changing the characteristic impedance of the transmission line coupled to the second variable, depending on the applied voltage; And is connected to the transmission line coupled to the first, the resonance frequency including a variable voltage applying means for applying a variable voltage to the adjusting means. ; 4. An important use of the invention ; The present invention used to fight like a voltage-controlled oscillator.
