Resonators TRIZ Cases
- Post-Bonding Tuning of Dielectric Resonator Filters
Drilling tuning holes on outer faces adjusts resonant frequencies in bonded dielectric filters.
- Dual-Mode Resonator Coupling Groove Design
Asymmetric coupling grooves enable independent positive and negative coupling control, resolving design complexity in dual-mode resonators.
- Dielectric Core Tunable Filters for High Power Microwave Applications
Low loss machined dielectric resonators resolve the contradiction between high quality factor and fast electrical tuning speed.
- Multimode Resonator Split Chamfer Tuning
A multimode radio frequency resonator uses a split chamfer to perturb magnetic fields for independent mode tuning.
- Reconfigurable Balanced Bandpass Filters Using Varactor Tuning
Varactor diodes replace mechanical tuning elements in high-order balanced bandpass filters, achieving wideband common-mode suppression and low insertion loss.
- Variable Interval Dielectric Resonator Band Pass Filter
Movable dielectric resonators adjust the opposing interval to vary the center frequency while maintaining a high Q factor.
- Embedded Interdigital Defected Ground Structure for Harmonic Suppression
A resonant unit integrates an embedded interdigital structure within a defected ground plane to generate multiple resonant frequencies.
- Filter Structure with Resonance Holes for Frequency Response
Resonance holes and a pattern layer improve frequency response while mitigating spurious responses in communication systems.
- Threadless Tuning Elements for Coaxial Resonators
Threadless tuning elements in coaxial resonator bores eliminate metallic abrasion and passive intermodulation from threaded connections.
- Microwave Cavity Resonator Miniaturization via Capacitive Loading
Capacitor elements create a capacitance gap to shorten the resonator element below quarter-wavelength physical length while maintaining electrical stability.
