TUNABLE MATCHING NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022226 titled 'TUNABLE MATCHING NETWORK

Simplified Explanation

The patent application describes systems and methods for generating a radio frequency (RF) signal using a digital-to-analog converter (DAC) with a transmission frequency within a wide range. The output reactance of the DAC is coupled to one or more antennas, corresponding to the transmission frequency of the RF signals. Various embodiments of the DAC include circuitry for tuning the output reactance to shift the center frequency and select a transmission frequency range for providing the RF signals.

  • Explanation of the patent/innovation:
  • The patent describes a system for generating RF signals using a DAC with a wide transmission frequency range.
  • The output reactance of the DAC is connected to antennas to correspond to the transmission frequency of the RF signals.

Original Abstract Submitted

systems and methods for generating a radio frequency (rf) signal by a digital-to-analog converter (dac) with transmission frequency within a wide transmission frequency range is described. an output reactance of the dac coupled (directly or indirectly) to one or more antennas corresponds to the transmission frequency of the rf signals. multiple embodiments of the dac are described to include circuitry for tuning the output reactance of the dac, and therefore, shifting a center frequency to select a transmission frequency range (from multiple transmission frequency ranges) for providing the rf signals.
