PHASE SHIFT METHOD USING PHASE SHIFTER AND FREQUENCY QUADRUPLER, AND DEVICE PERFORMING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240048199 titled 'PHASE SHIFT METHOD USING PHASE SHIFTER AND FREQUENCY QUADRUPLER, AND DEVICE PERFORMING SAME
Simplified Explanation
The disclosed patent application describes a method and device for phase shifting and frequency quadrupling an input signal in super high-frequency lo beamforming technology. Here is a simplified explanation of the abstract:
- The method involves shifting the phase of an input signal using a phase shifter.
- The frequency of the phase-shifted input signal is then up-converted using a frequency quadrupler.
- The up-conversion is achieved by multiplying the frequency of the phase-shifted signal by a multiplication coefficient (n).
Potential applications of this technology:
- Super high-frequency lo beamforming technology: The disclosed method and device can be used in beamforming systems operating at super high frequencies, such as in radar systems or wireless communication systems.
Problems solved by this technology:
- Phase resolution decrease: When passing through a frequency quadrupler, there is a decrease in phase resolution. The disclosed method and device overcome this issue, ensuring accurate phase shifting even after up-conversion.
Benefits of this technology:
- Improved phase resolution: By overcoming the phase resolution decrease, the disclosed method and device provide improved accuracy in phase shifting, resulting in more precise beamforming and signal processing.
- Synchronization with conventional frequency quadruplers: The technology can be synchronized with existing frequency quadruplers, allowing for seamless integration into current systems without the need for major modifications.
