Abstract
A radio-frequency apparatus includes an integrated circuit. The integrated circuit includes receiver analog circuitry, receiver digital circuitry, a digital-to-analog converter, and a signal selector. The receiver analog circuitry receives radio-frequency signals, and provides a first digital signal. The receiver digital circuitry receives the first digital signal, and provides a second digital signal. The digital-to-analog converter converts the second digital signal into a first analog signal. The signal selector receives the second digital signal and the first analog signal, and selectively provides one of the second digital signal and the first analog signal as an output signal of the integrated circuit.
