Title:
WAVEGUIDE-TYPE DIELECTRIC FILTER
Document Type and Number:
Japanese Patent JP2002043807
Kind Code:
A
Abstract:
To obtain a waveguide-type dielectric filter which makes sure input/ output connection and shielding, so as to improve the filter characteristic.
The input/output electrodes of a dielectric block 10 are connected to a conductor pattern provided on a double-sided wiring board 20, and terminals and led out from the conductor pattern. A grounding conductor pattern is also formed on the double-sided wiring board 20; moreover the double- sided wiring board 20 is mounted on a board 30 on which a shielding pattern has been formed; and then the dielectric block 10 and boards 20 and 30 are jointed together.
