CANCELLATION CIRCUIT USING DIGITAL TO TIME CONVERTER
A cancellation circuit includes a limiter connected to an output of a first transmitter power amplifier that converts in input sinewave to a digital square wave and a digital to time converter (DTC) connected to the limiter. A RF digital to RF converter is connected to the DTC that converts the digi...

| description | A cancellation circuit includes a limiter connected to an output of a first transmitter power amplifier that converts in input sinewave to a digital square wave and a digital to time converter (DTC) connected to the limiter. A RF digital to RF converter is connected to the DTC that converts the digital square wave input into an analog RF output. A cancellation amplifier with an input receives an output from the RF digital to RF converter and has an output connected to an output of a second transmitter power amplifier. The cancellation amplifier produces a cancellation signal to cancel an interference signal at the output of the second transmitter power amplifier from the output of the first transmitter power amplifier. A power detector is connected to the output of the second power amplifier that produces a power value detected at the output of the second power amplifier. |
