  • Patent number: 9190974
    Abstract: A method and a device for controlling the level of a pulsed high-frequency signal amplify or respectively attenuate an un-pulsed high-frequency signal with an amplification or attenuation element adjustable with regard to its amplification or attenuation factor. A pulsed high-frequency signal is generated by a pulse modulator controlled by a pulse signal from the un-pulsed high-frequency signal. At the output of the pulse modulator, a signal level of the pulsed high-frequency signal is measured by a high-frequency detector. The amplification or attenuation factor of the amplification or attenuation element is adjusted with a level controller controlled by the measured signal level. To control the level controller, the measured signal level of the pulsed high-frequency signal is linked to the measured signal level of the pulse 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.
