  • Patent number: 10700696
    Abstract: A control circuit for signal sampling of an analog RF signal includes: a spectrum monitoring circuit for monitoring the analog RF signal to determine a frequency of the analog RF signal; a tunable clock source for generating a tunable sampling clock for sampling the analog RF signal; a sample clock tuning circuit for controlling the tunable clock source and selecting a sample clock frequency of the tunable sampling clock that provides a predetermined ratio between the sample clock frequency of the tunable sampling clock and a center frequency of the analog RF signal; and an Analog-to-Digital Converter (ADC) for sampling the analog RF signal using the tunable sampling clock.

  • Patent number: 10568224
    Abstract: A configurable radio frequency system. The system includes: a plurality of radio frequency cells connected in a cascade. Each of the radio frequency cells includes an input switch connected to an input of the radio frequency system, an output switch connected to an output of the radio frequency system, and a plurality of elements, each of the elements being connected between the input switch and the output switch. The input switch and the output switch are configured, depending on their respective settings, to cause a radio frequency signal path from an input of the cell to an output of the cell to include one of the elements. The plurality of elements in each cell includes a band pass filter, an attenuator, a through path, an amplifier, and a mixer.
