Multiple-Port Networks TRIZ Cases
- Self-Aligning EMF Sensor Structure to Prevent Air Gaps
Frustum-shaped conductor sections self-align with dielectric elements to prevent air gaps, arcing, and EMF sensor calibration drift.
- Base Die RF Filter Structures for Stacked Chiplet Noise Suppression
Integrated common mode choke, notch filter, and Faraday cage structures suppress RF noise in stacked chiplet packages without costly discrete shielding.
- Directional Coupler Filter Switching for ESD-Protected Frequency Response
Grounding unselected thin-film filters prevents electrostatic discharge damage and preserves directional coupler frequency characteristics.
- RF Power Amplifier Circuit With Shared 2G/3G/4G Signal Paths
A single RF power amplifier handles 2G, 3G, and 4G signals, using filtering for 2G harmonic suppression and lower board complexity.
- Parallel Inverter AC Filter Circuit for Resonance Damping
A split LC filter with a series reactor and damping resistor suppresses resonant current in parallel converters while reducing filter size.
- Digital Phase Shifter Grounding Layout for Even Stage Delay
An extension grounding line moderates uneven stage phase shifts in cascaded digital phase shifters, improving delay consistency across modes.
- HF Front-End Circuit Phase Shifting for Carrier Aggregation Isolation
A phase shifter between duplexer and diplexer adapts harmonic impedance to suppress intermodulation during carrier aggregation.
- Multilayer Filter Module Layout to Limit Inductor Coupling
Vertical inductor placement on a multilayer filter module limits electrode coupling and preserves transmission characteristics in a smaller substrate.
- Transformer Matching Network With Tunable Notch for LO Spur Rejection
Interwinding capacitance in a transformer matching network creates a tunable notch that suppresses LO spurs without degrading mmWave signal integrity.
- Capacitor Life Estimation Using Telemetry and Reliability Curves
Telemetry, environmental inputs, and reliability curves are combined to estimate capacitor life consumed more accurately under real operating conditions.
- Embedded Inductor Structure for Compact Semiconductor LC Packaging
By embedding an inductor and capacitors in redistribution layers, this package shortens signal paths, cuts parasitic impedance, and boosts bandwidth.
- LTCC Five-Order Band-Pass Filter for Wide Passband and Low Loss
A five-resonator LTCC filter uses cross-coupling and series inductors to widen passband, cut insertion loss, and deepen out-of-band suppression.
- Motor Drive Filter Topology for PWM Cable Overshoot Suppression
Common-mode choke inductors and grounded capacitors curb PWM cable overshoot and bearing-damaging currents in remote motor drives.
