  • Method and apparatus for processing radio frequency input signals and providing interfering radio frequency output signals
    Patent number: 10761401
    Abstract: An apparatus includes a signal modulator configured to receive a radio frequency (RF) input signal having frequency bands and spanning a first frequency range within a second frequency range, and provide down-converted signals by converting each frequency band of the RF input signal down to a target frequency range. The apparatus further includes digital RF memories (DRFMs) configured to provide intermediate interfering signals by modulating at least one of the down-converted signals, and an interfering signal generator configured to provide up-converted signals by converting the intermediate interfering signals collectively up to a third frequency range, wherein the third frequency range is within the second frequency range, and provide an interfering RF output signal by combining the up-converted signals, wherein the interfering RF output signal spans the third frequency range.
