Waveguide Type Devices TRIZ Cases
- Phase Shifter Circuit for Linear Digital Phase Control
Discrete switching and I/Q magnitude control make output phase change linearly with control signals for more accurate phase setting.
- Liquid Crystal Phase Shifter With Split Ring Resonator Filtering
A liquid crystal layer and split ring resonator combine phase shifting and filtering to cut RF front-end volume and insertion loss.
- Microwave Gyromagnetic Circulator Pin Structure for Stable Miniaturization
A pin-and-solder tank structure lets a microwave gyromagnetic circulator shrink without bandwidth loss while improving joint stability.
- PCB-Mounted Resonator Heads for Consistent RF Filter Coupling
A PCB fixes multiple resonator heads in precise positions to reduce height variation, stabilize coupling, and improve RF filter loss and delay.
- Free-Standing YIG Frequency Selective Limiter for Wider Bandwidth
A free-standing YIG film on a conductive plane expands FSL bandwidth and upper frequency cutoff without exotic circuit topologies.
- Curved Polarization Rotator for D-Band Impedance Matching
A curved D-Band polarization rotator uses spline or hybrid arc-rectangle geometry to improve bandwidth control and impedance matching.
- MEMS Phase Shifter Bridge Structure to Reduce Adhesion Loss
A non-even isolating surface lets a MEMS bridge tune coplanar waveguide capacitance for phase delay while reducing adhesion and insertion loss.
- Waveguide Gasket Ribbon Structure for RF Gap Sealing
Flexible conductive ribbon members seal waveguide gaps to limit RF leakage while preserving high-frequency transmission and lowering cost.
- Multi-Row Digital Phase Shifter Ground Layout for Stable Phase Shift
A one-point ground connection on the front row limits interference in multi-row digital phase shifters and preserves phase shift quantity.
- Ferrite Nonreciprocal Circuit Tuning for Wideband Impedance Matching
Variable DC magnetic field control tunes ferrite permeability and center frequency to widen operation and cut insertion loss.
- TiO2 Bandpass Filter Deposition to Prevent Cavity Layer Cloudiness
Periodic deposition stops cool the substrate to suppress TiO2 cavity-layer crystallization, improving transmittance and reducing scattering.
- Planar Interdigital Cavity Filter for Lower Size and Weight
Planar interdigital resonators linked by connection strips shrink cavity filter size and weight while easing tuning and manufacturing.
- MEMS Phase Shifter Film Bridge Layout With Fewer Bias Lines
Shared biasing through signal and reference lines lets short film bridges shift phase with fewer pins, reducing collapse risk and improving yield.
- Microwave Circulator Via Array for Lighter Robust Ferrimagnetic Biasing
A single-layer via-filled ferrimagnetic array cuts circulator weight and fragility while preserving one-way microwave signal routing.
