ACOUSTIC RESONATOR LID FOR THERMAL TRANSPORT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18488277 titled 'ACOUSTIC RESONATOR LID FOR THERMAL TRANSPORT

The patent application describes an apparatus for filtering radio frequency signals, consisting of a substrate, a membrane with piezoelectric material, and an interdigital transducer (IDT) with interleaved fingers. The membrane is positioned between the substrate and a lid, creating two cavities with different heights.

  • The apparatus includes a membrane with piezoelectric material.
  • An interdigital transducer (IDT) with interleaved fingers is coupled to the membrane.
  • The membrane is arranged between the substrate and a lid, creating two cavities with different heights.
  • The first cavity between the lid and the membrane is greater than the pitch of the interleaved fingers and at most four times greater than the second cavity height.

Potential Applications: - Wireless communication devices - Radar systems - Satellite communication systems

Problems Solved: - Filtering out unwanted radio frequency signals - Improving signal quality and reliability

Benefits: - Enhanced signal filtering capabilities - Improved performance of wireless communication systems - Increased signal clarity in radar and satellite systems

Commercial Applications: Title: "Advanced RF Signal Filtering Apparatus for Wireless Communication Devices" This technology can be utilized in the development of advanced wireless communication devices, radar systems, and satellite communication equipment. It has the potential to improve signal filtering and enhance overall performance in various commercial applications.

Prior Art: No prior art information is provided in the abstract.

Frequently Updated Research: There is no information on frequently updated research related to this technology at the moment.

Questions about RF Signal Filtering Apparatus: 1. How does the membrane with piezoelectric material contribute to signal filtering in the apparatus? 2. What are the specific advantages of using an interdigital transducer with interleaved fingers in this filtering system?


Original Abstract Submitted

An apparatus for filtering radio frequency signals is provided. The apparatus includes a substrate and a membrane coupled to the substrate that includes piezoelectric material. The apparatus also includes an interdigital transducer (IDT) coupled to the membrane and includes a plurality of interleaved fingers. The apparatus also includes a lid, in which the membrane is arranged between the substrate and the lid with a first cavity having a first height between the lid and a first main surface of the membrane and a second cavity having a second height between the substrate and a second main surface of the membrane that opposes the first main surface. Moreover, the first height between the lid and the first main surface of the membrane is greater than a pitch of at least one pair of interleaved fingers of the plurality of interleaved fingers and at most four times greater than the second height.
