Title:
FILTER, MULTIPLEXER, AND COMMUNICATING DEVICE
Document Type and Number:
Japanese Patent JP3632576
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a filter that cancels problems regarding a conductor loss due to I/O line and connectivity with a wavegudie and an NRD guide, when the I/O line such as microstrip and suspended lines are used as a line for the excitation of a resonator, a mlutiplexer, and to provide a communicating device having the filter and multiplexer.
SOLUTION: Electrodes 2 and 3 are formed on both surfaces of a dielectric plate 1, and at the same time, mutually opposing electrode openings 4a to 4e and 5a to 5e are provided, each electrode opening being allowed to operate as the resonator, and the resonator at an end section is connected directly to the waveguide comprising a package base 61 and a package cover 62.
