Abstract:
A radar fill level measurement device for determining a fill level of a medium is provided, including a radar module to generate a transmission signal of at least 60 GHz; and an antenna coupled to the module and to transmit the signal to a surface of the medium and to receive a reflected signal, the module including a phase-locked loop including a push-push oscillator and a phase detector, the oscillator including a first and second outputs, a duplexer coupled between the push-push oscillator and the antenna, and a frequency multiplier coupled between the oscillator second output and the duplexer, the oscillator first output being directly wired to the phase detector input, the duplexer being coupled to the antenna, the phase detector including a reference input and a phase detector output coupled to an oscillator control input. A method for operating a radar fill level measurement device is also provided.

Claim (Index 1):
A radar fill level measurement device for determining the fill level of a medium, the radar fill level measurement device comprising:\n a radar module configured to generate a transmission signal having a transmission frequency of at least 60 GHz; and at least one antenna coupled to the radar module and being configured to transmit the transmission signal to a surface of the medium and to receive a signal reflected from the surface, wherein the radar module comprises:\n a phase-locked loop comprising a push-push oscillator and a phase detector, wherein the push-push oscillator comprises a first output configured to transmit a first output signal, and a second output configured to transmit a second output signal, \n a duplexer coupled between the push-push oscillator and the at least one antenna, configured to separate the transmission signal and the received signal, and \n a frequency multiplier coupled between the second output of the push-push oscillator and the duplexer, configured to multiply the frequency of the second output signal of the push-push oscillator, \n wherein the first output of the push-push oscillator is directly wired to an input of the phase detector, wherein the duplexer is coupled to the at least one antenna such that the transmission signal is emittable via the at least one antenna based on the second output signal of the push-push oscillator, wherein the phase detector comprises a reference input configured to receive reference frequency signals and a phase detector output that is coupled to a control input of the push-push oscillator, and wherein the phase detector is configured to detect a phase difference between the reference frequency signal and the second output signal of the push-push oscillator, and to transmit, at the phase detector output, a regulation signal configured to regulate the push-push oscillator, the regulation signal being correlated with the detected phase difference, to the control input of the push-push oscillator.
