Two-Way Amplifiers TRIZ Cases
- Bi-Directional Amplifier Isolation Using Adaptive Digital Filtering
Adaptive digital filtering removes downstream leakage before upstream amplification, improving isolation and signal quality in broadband networks.
- RF Power Detector Using Dual Voltage Rails for High-Level Sensing
A secondary voltage rail bleeds detector current to preserve accurate RF power sensing while easing demand on the primary rail.
- RF Power Detector Using Split Rails for Wide Dynamic Range
A split-rail RF power detector shares detector current across two voltage rails to preserve wide-range power sensing without redesigning power management circuits.
- QBPA RF Front End With Feed-Forward Leakage Cancellation
A QBPA-based RF front end injects a cancellation signal to suppress leakage and reflections while improving T/R isolation with low insertion loss.
- Neutralized Differential Bi-Directional Amplifier Without T/R Switch Loss
Cross-coupled differential pairs replace lossy T/R switching, preserving bidirectionality while reducing passive loss and system complexity.
