  • Method and arrangement for generating a frequency-modulated signal
    Patent number: 8476985
    Abstract: In order to generate a broadband, frequency-modulated output signal, of which the carrier frequency is adjustable within a wide frequency range, a frequency-modulated signal is generated on an arbitrary, fixed carrier frequency, which is then converted into IQ signals, and the IQ signals generated in this manner are combined with the desired carrier frequency by IQ modulation to form the frequency-modulated output signal. By preference, the generated IQ signals are low-pass filtered before the IQ modulation.
    Type: Grant

    Date of Patent: July 2, 2013
