FILTER DEVICE AND HIGH-FREQUENCY FRONT-END CIRCUIT PROVIDED WITH THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18238661 titled 'FILTER DEVICE AND HIGH-FREQUENCY FRONT-END CIRCUIT PROVIDED WITH THE SAME

Simplified Explanation

The filter device described in the abstract is a complex electronic component that utilizes resonators to transmit signals from an input terminal to an output terminal. Here is a simplified explanation of the patent application:

  • The filter device consists of a main body with resonators that are electromagnetically coupled to each other.
  • Each resonator has a first path connected to nodes via capacitors to the ground terminal, and a second path connected directly to the ground terminal without capacitors.
  • The second paths of two resonators are partially shared, creating a unique configuration.
  • The filter device also includes a third path connected to the nodes of two resonators.

Potential Applications: - Telecommunications - Signal processing - Wireless technology

Problems Solved: - Filtering out unwanted signals - Improving signal transmission quality

Benefits: - Enhanced signal processing capabilities - Improved signal clarity - Increased efficiency in electronic devices

Potential Commercial Applications of this Technology: - Mobile phones - Satellite communication systems - Radar systems

Possible Prior Art: - Similar filter devices using resonators and capacitors in electronic circuits

Unanswered Questions: 1. How does the shared second path of the resonators affect signal transmission efficiency? 2. What specific electronic devices can benefit the most from this filter device technology?


Original Abstract Submitted

A filter device includes a main body, an input terminal, an output terminal, a ground terminal, and resonators. The resonators are located in the main body and are electro-magnetically coupled with each other so as to transmit a signal from the input terminal to the output terminal. Each of the resonators includes a first path connected from nodes via capacitors to the ground terminal, and a second path connected from the nodes to the ground terminal without passing through the capacitors. The second path of a first resonator and the second path of a second resonator are partially shared. The filter device further includes a third path connected with the node of the first resonator and the node of the second resonator.
