Abstract
The present invention comprises baluns 2a, 2b which convert balanced line signals and unbalanced line signals mutually, and filters 3a, 3b which are electrically connected to the baluns 2a, 2b and pass or attenuate the predetermined frequency bands. Electrode layers 15a-22a, 25a, 41, 42, 43 which compose the electrode patterns of the baluns 2a, 2b and the filters 3a, 3b, and the dielectric layers 30-39 are integrally stacked.
Claims33
A complex high frequency component comprising:
- a balun for mutually converting a balanced line signal and an unbalanced line signal;
- and
- a filter for passing or attenuating predetermined frequency bands, said filter being electrically connected to said balun,
- said complex high frequency component further comprising:
- an electrode layer including a first electrode layer which comprises electrode patterns for said balun and a second electrode layer which comprises electrode patterns for said filter;
- a dielectric layer, wherein said dielectric layer and said first and second electrode layers are integrally stacked, and wherein said first electrode layer comprising the electrode pattern of said balun and said second electrode layer comprising the electrode pattern of said filter are arranged in different positions from each other on said dielectric layer, and
- a first shield electrode layer disposed between said first electrode layer comprising the electrode pattern of said balun and said second electrode layer comprising the electrode pattern of said filter.
