Electrical Connection Printed Elements TRIZ Cases
- High-Frequency Circuit Shield Via Layout for Crosstalk Suppression
Rectangular shield vias tied to multiple grounds block electromagnetic leakage between closely spaced signal lines and reduce crosstalk tolerance issues.
- SIW Coaxial Power Divider-Combiner With Broadband Impedance Matching
A multilayer SIW coaxial divider-combiner uses impedance transformation sections to cut loss, reduce bulk, and widen RF bandwidth.
- Backplane Footprint Using Shadow Vias for High-Speed Differential Pairs
Conductive shadow vias between differential signal vias reshape the electric field to cut crosstalk in dense high-speed connector backplanes.
- PCB Cavity Resonator Oscillator Layout for Low Phase Noise
Via-coupled PCB integration places the cavity resonator close to the amplifier, cutting phase noise while simplifying tuning and assembly.
- Single-Layer PCB 180° Hybrid Coupler With Strong Broadband Coupling
Quarter-wave stubs and a delay line boost coupling on a single-layer PCB 180° hybrid coupler while keeping broad bandwidth and low return loss.
