Coupling Devices TRIZ Cases
- RF Power Divider With Quarter Wave Transformers
A power divider circuit uses quarter wave transformers and resistors to split signals.
- Diagonal Differential Phase Shifter Balancing Impedance
A diagonal coupled line coupler balances characteristic impedance across metal layers.
- Cast Orthomode Transducer Housing for Cost-Effective Multi-Frequency Production
Interchangeable casting inserts standardize the outer housing shape across frequencies, reducing manufacturing costs and production complexity.
- Dielectric Waveguide Coupler for Air Waveguides
A directional coupler uses a dielectric waveguide with a coupling slot to interface an air waveguide.
- Switch Circuit Resonant Impedance Matching for Millimeter Wave Isolation
Resonant circuits transform branch path impedance near short on the Smith chart to achieve over 100 dB isolation while maintaining wide band operation.
- Compact 5x6 Butler Matrix Design for Multi-Beam Antennas
Segmenting a 5x6 Butler matrix into two 3x3 sub-matrices reduces physical size and signal loss while maintaining multi-wave beam generation capability.
- Compact Multiport Waveguide Switches Using PIN Diode Loads
Replacing mechanical rotation with solid-state PIN diodes eliminates bulky moving parts while maintaining high power handling for multiport configurations.
- Thermoset Plastic Waveguide Components for Millimeter Wave Electronics
Reactive transfer molding of thermoset plastic waveguides eliminates weight penalties and thermal instability found in machined metal components.
- Directional Coupler Auxiliary Ground Layer Impedance Control
Auxiliary ground layer reduces impedance deviation in non-overlapping regions by maintaining specific distance ratios relative to ground planes.
