Resonators TRIZ Cases
- 30 GHz Dielectric Filter Resonator Configuration
Segmented rectangular dielectric resonators achieve high bandwidth and low temperature drift by replacing hollow conductors to reduce weight.
- Base Station Filter With Direct Resonant Cavity Coupling
Direct cavity coupling replaces complex indirect structures, improving outband suppression and batch consistency for high-channel filters.
- Dielectric Filter Via Hole Partition Ring Capacitive Coupling
A dielectric filter uses a via hole and conductive partition ring to establish capacitive coupling between resonant cavities.
- Ferrite Filter Aperture-Coupled Fin Lines
Asymmetric coupling apertures suppress auxiliary modes in aperture-coupled fin line filters, reducing insertion loss.
- Stacked Substrate Integrated Waveguide Filter for Compact Microwave Design
Stacked cavities coupled by right triangle slots shift parasitic passbands from 2f0 to 4f0, enhancing out-of-band suppression in microwave circuits.
- Ceramic Block Filter Resonator Edge Shaping
Rounding resonator cavity edges in ceramic block filters reduces resistive losses and power handling limits caused by current crowding.
- Folded Hat Cavity Filter for Picocell Base Stations
A folded hat resonator design enables compact microwave cavity filters for picocell base stations.
