DISTRIBUTED-ELEMENT FILTER FOR MMWAVE FREQUENCIES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240297672 titled 'DISTRIBUTED-ELEMENT FILTER FOR MMWAVE FREQUENCIES
The patent application describes frequency-filtering circuitry that can reject power from a wireless signal with an undesired frequency while minimizing power loss from a signal with a desired frequency. This is achieved using distributed elements instead of lumped elements.
- The circuitry can reject at least 5 decibels of power from a signal above 32 gigahertz, while causing a power loss of at most 1.1 decibels to a signal below 29.5 gigahertz.
- It includes a main branch, a first parallel branch, and a second parallel branch connected via connecting traces.
- The first and second connecting traces intersect the main branch and the respective parallel branches to achieve the desired frequency filtering.
Potential Applications: - Telecommunications equipment - Radar systems - Satellite communication devices
Problems Solved: - Efficient rejection of unwanted frequencies - Minimization of power loss in desired frequencies
Benefits: - Improved signal quality - Enhanced performance in high-frequency applications - Cost-effective design using distributed elements
Commercial Applications: "Advanced Frequency-Filtering Circuitry for Telecommunications and Radar Systems"
Questions about the technology: 1. How does the use of distributed elements improve frequency filtering compared to lumped elements? 2. What are the specific advantages of rejecting power from signals above 32 gigahertz while minimizing loss in signals below 29.5 gigahertz?
Original Abstract Submitted
frequency-filtering circuitry is disclosed that rejects power of a wireless signal having an undesired frequency while causing a decreased power loss to a wireless signal having a desired frequency using distributed elements, rather than lumped elements. the frequency-filtering circuitry may reject at least 5 decibels of power of a wireless signal having a frequency over 32 gigahertz, while causing a power loss of at most 1.1 decibels to a wireless signal having a frequency lower than 29.5 gigahertz. the frequency-filtering circuitry may include a main branch, a first parallel branch coupled and parallel to the main branch via a first connecting trace, and a second parallel branch coupled and parallel to the main branch via a second connecting trace. the first connecting trace intersects the main branch and the first parallel branch, and the second connecting trace intersects the main branch and the second parallel branch.
