  • Spread Spectrum ASK/OOK Transmitter
    Publication number: 20070253468
    Abstract: An ASK/OOK transmitter includes a frequency-shift keying (FSK) modulator receiving an input bit sequence and generating a FSK modulation signal indicative of the input bit sequence, a frequency generation circuit receiving the FSK modulation signal and generating a carrier signal having a first frequency where the frequency of the carrier signal is shifted by the FSK modulation signal to form a wideband carrier signal, an amplitude-shift keying (ASK) modulator receiving input data and generating an ASK modulation signal indicative of the input data, and a power amplifier coupled to receive the wideband carrier signal as an input signal and the ASK modulation signal as a control signal. The power amplifier provides a spread spectrum ASK transmission signal where the ASK modulation signal modulates the wideband carrier signal to form the spread spectrum ASK transmission signal.
