Radio frequency digital to analog converter with power amplifiers
A recently granted patent (Publication Number: US11979118B2) discloses a radio frequency digital to analog converter (RF-DAC) featuring a unique design with multiple power amplification modules (PAMs) and a transformer. The RF-DAC includes power amplifiers control units and a transformer control unit that work together to activate specific power amplifiers and control transformer parameters during each cycle. The transformer receives output signals from the PAMs and outputs a signal reflecting digital information represented by the control signals. The RF-DAC is capable of performing multiple cycles, with each PAM receiving positive and negative RF pulses, and the load includes a filter to provide a filtered output signal.
Furthermore, the patent details a method for radio frequency digital to analog conversion, outlining the steps involved in determining transformer parameters, activating power amplifiers, amplifying RF signals, and transferring the amplified signals through the transformer to generate an output signal. The method emphasizes the linear relationship between digital information values and the RF-DAC's output power. Additionally, the method involves translating control signals to different points on the RF-DAC power curve to ensure efficient signal processing. Overall, the patented RF-DAC and method offer a novel approach to radio frequency signal conversion with precise control over power amplification and signal output.
