==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.


==Original Abstract Submitted==

disclosed are a phase shift method and a device performing same, the method comprising the steps of: shifting a phase of an input signal by a phase shifter, and up-converting, by a frequency quadrupler, a frequency of the input signal of which the phase has been shifted, by a multiplication coefficient (n). according to the phase shift method and the device performing same, it is possible to overcome a phase resolution decrease that occurs when passing through a frequency quadrupler in super high-frequency lo beamforming technology synchronized with a conventional frequency quadrupler.
