DIGITAL PHASE SHIFTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18018147 titled 'DIGITAL PHASE SHIFTER
The digital phase shifter described in the patent application consists of multiple digital phase shift circuits connected in a cascade configuration. Each circuit includes signal lines, inner lines, outer lines, grounding conductors, and electronic switches.
- The digital phase shifter can operate in a low-delay mode or a high-delay mode, depending on whether return currents flow in the inner lines or outer lines.
- A phase shift quantity moderator is included to address any unevenness in the phase shift quantity among the digital phase shift circuits.
- The phase shift quantity moderator helps to ensure consistent performance across all circuits.
Potential Applications: - Telecommunications - Radar systems - Satellite communication - Antenna arrays
Problems Solved: - Inconsistencies in phase shift quantities among digital phase shift circuits - Need for precise control of phase shifting in electronic systems
Benefits: - Improved signal processing capabilities - Enhanced performance in communication systems - Greater flexibility in adjusting phase shifts
Commercial Applications: Title: Advanced Digital Phase Shifter for Communication Systems This technology could be utilized in the development of high-performance communication systems for various industries, including telecommunications, defense, and aerospace.
Questions about the technology: 1. How does the phase shift quantity moderator help to ensure consistent performance in the digital phase shifter? The phase shift quantity moderator moderates any unevenness in the phase shift quantity among the digital phase shift circuits, ensuring that all circuits operate with the desired phase shift accuracy.
2. What are the potential advantages of using a digital phase shifter with multiple circuits in a cascade configuration? Using multiple circuits in a cascade configuration allows for more precise and flexible control of phase shifting, leading to improved performance in communication systems.
