Patent ID: 7398074

Claim:
An integrated transceiver circuit, comprising: a reception path comprising: a mixer unit configured to demodulate a received signal; an analog/digital converter unit connected downstream from the mixer unit; a first voltage controlled oscillator; a first frequency divider connected between the first voltage controlled oscillator and the mixer unit, and configured to obtain a demodulation frequency for use by the mixer unit; and a second frequency divider connected between the first voltage controlled oscillator and the analog/digital converter unit, and configured to obtain a sampling frequency for use by the analog/digital converter unit; and a transmission rath comprising: a modulator configured to modulate a signal to be transmitted; a second voltage controlled oscillator; a third frequency divider connected between the second voltage controlled oscillator and the modulator, and configured to obtain a modulation frequency for use by the modulator; a digital/analog converter unit connected upstream of the modulator; and a fourth frequency divider connected between the second voltage controlled oscillator and the digital/analog converter unit, and configured to obtain a sampling frequency for use by the digital/analog converter unit.
