Phase Shifting Networks TRIZ Cases
- Digital Phase Shifter Ground Layout for Larger Low-Frequency Phase Steps
Separated ground conductors and outer lines raise high-delay inductance, widening low-frequency phase shift differences in cascaded circuits.
- Stacked PIN Diode Switch Structure for Self-Matched Linearity
A centrosymmetric stacked PIN diode structure self-matches thickness and doping to improve switch linearity and cut chip packaging cost.
- Phase Shifter Compensation Circuit for Low-Loss Phase Accuracy
Compensation circuits correct synthesized signal phase errors across frequency bands, preserving phase accuracy without extra polyphase filter stages.
- Varactor Reflection Phase Shifter for Low-Loss Beam Steering
A quadrature hybrid steers RF energy to bias-tuned varactors, delivering compact low-loss phase shifting for phased-array beam steering.
- RF Phase Shifter Circuit for Transmit-Receive Crosstalk Cancellation
An adjustable varactor-based RF phase shifter cancels transmit leakage in receive paths, improving SNR and reducing radar front-end complexity.
- Cascaded Bipolar Phase Shifter With Low-Distortion Delay Stages
Variable current sources in cascaded delay stages adjust phase shift while reducing distortion, delay, and the need for RC filters.
- Liquid Crystal Phase Shifter Dielectric Constant Compensation
Feedback loop adjusts direct-current bias voltage based on resonant circuit detection to compensate for phase shift deviations caused by external environment.
- Meandered Phase Shifter With Slidable Wiper
Sliding wipers along meandered conductive traces replace rotating mechanisms, reducing device size while maintaining precise phase control.
