TUNABLE DIFFERENTIAL TRANSMISSION LINE SEGMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18274260 titled 'TUNABLE DIFFERENTIAL TRANSMISSION LINE SEGMENT

Simplified Explanation

The present application describes a tunable differential transmission line segment with a differential pair of signal line segments and a pair of tuning line segments that are capacitively coupled to the signal line segments and have a tunable element to change their impedance.

  • The differential transmission line segment includes:
    • A pair of signal line segments arranged in a first plane
    • A pair of tuning line segments arranged in a second plane parallel to the first plane
    • Capacitive coupling between the tuning line segments and the signal line segments
    • Tunable elements in the tuning line segments to adjust impedance

Potential Applications: This technology could be used in high-speed data transmission systems, RF circuits, and microwave communication systems.

Problems Solved: This innovation helps in fine-tuning impedance matching in transmission lines, reducing signal distortion, and improving overall signal integrity.

Benefits: The tunable differential transmission line segment offers improved signal quality, increased data transmission speeds, and enhanced performance in high-frequency applications.

Potential Commercial Applications: This technology could be valuable in telecommunications equipment, networking devices, test and measurement instruments, and other high-frequency electronic systems.

Possible Prior Art: Prior art may include similar tunable transmission line segments used in RF and microwave applications, but specific details would need to be researched.

Unanswered Questions: 1. What specific materials are used in the construction of the tunable elements in the tuning line segments? 2. Are there any limitations to the tunable range of impedance adjustment in this technology?


Original Abstract Submitted

The present application concerns a tunable differential transmission line segment, comprising a differential pair of signal line segments () arranged in a first plane. A pair of tuning line segments () is arranged in a second plane substantially parallel to the first plane, wherein the pair of tuning line segments () is at least capacitively coupled to the differential pair of signal line segments (). The pair of tuning line segments () is connected with its respective end terminals () to a common reference potential and further comprises a tunable element () arranged between a first portion () and a second portion () of the pair of tuning line segments () and configured to change the impedance of the pair of tuning line segments ().
