Coupling Devices TRIZ Cases
- Hybrid Coupler Bandwidth via Segmented Transmission Lines
Segmented transmission lines with varying electrical lengths expand operational bandwidth in a hybrid coupler without coiling, maintaining thermal capability.
- Miniaturized Half-Wave Balun Using Capacitive Loading
Capacitive loading on shortened transmission lines suppresses common mode response in a miniaturized half-wave balun, solving size and loss trade-offs.
- Steerable FMCW Radar Transceiver With Circular Polarization
Phase shifting circuits in a transceiver generate circularly polarized waves to enable simultaneous transmit and receive operations.
- High-Frequency Module Directional Coupler Isolation via 3D Inductor Integration
A high-frequency module directional coupler integrates an impedance adjustment portion with a substrate inductor to enhance isolation characteristics.
- Microstrip Coupler Slot Antenna RF Waveguide
Slot antenna eliminates λ/4 short circuit components, reducing assembly tolerance sensitivity and manufacturing costs.
- Directional Coupler Inductive Compensation Single-Layer Directivity
Series inductors and parallel capacitance compensate for single-layer limitations, achieving high directivity without complex multi-layer structures.
