Title:
DISTRIBUTION CONSTANT RESONATOR AND DISTRIBUTION CONSTANT BAND PASS FILTER
Document Type and Number:
Japanese Patent JP2011119841
Kind Code:
A
Abstract:
To provide a distribution constant resonator capable of suppressing increase in loss of a main signal in the basic order resonant frequency, while oppressing a spurious component in the higher order resonant frequency.
The distribution constant resonator of a microstrip type has: a microstrip line conductor of high impedance prepared at the termination end side; and a microstrip line conductor of low impedance prepared at the open end side. An aperture is prepared within the microstrip line conductor of low impedance. A resistor and a tip-open stub are provided within the aperture. The tip-open stub has 1/4 lengths of wavelength to the higher order resonant frequency of the distribution constant resonator.
