Embodiment Construction

[0043] figure 1 is a block diagram of a radar level measuring device 10 according to an embodiment of the present invention.

[0044] The radar level measuring device 10 includes a radar module 12 for generating a transmission signal 11 and an antenna 14 coupled to the radar module 12 . The transmission signal 11 can be transmitted and / or emitted towards the surface 15 of the medium via the antenna 12 and the reception signal 13 reflected from the surface 15 can be received by the antenna 14 . The antenna 14 may be any type of antenna 14, such as a horn antenna, a lens antenna or a parabolic antenna. In this case, the transmission frequency of the transmission signal 11 is at least 60 GHz.

[0045] Radar module 12 includes a phase locked loop 16 including an oscillator 18 and a phase detector 20 coupled to oscillator 18 . Phase detector 20 may be a fractional phase detector 20 (also known as frac-N PLL) and / or an integer phase detector 20 (also known as int-N PLL). Further...

Abstract

A radar fill level measurement device for determining a fill level of a medium is provided, which includes a radar module to generate a transmission signal; and an antenna to transmit the transmissionsignal and to receive a reflected receiving signal, the radar module includes a phase-locked loop including an oscillator, a phase detector, and a frequency divider coupled between an output terminalof the oscillator and an input terminal of the phase detector and used for generating a frequency dividing signal, and a duplexer coupled between the oscillator and the antenna and coupled to the same output terminal of the oscillator with the frequency divider, the output terminal being directly wired to an input terminal of the duplexer, and the phase detector includes a reference input terminal used for receiving a reference frequency signal and a phase detector output terminal that is coupled to a control input terminal of the oscillator. The phase detector is used for detecting a phase difference between the reference frequency signal and the frequency dividing signal and transmitting an adjusting signal to the oscillator, and the adjusting signal is correlated to the phase difference and used for adjusting the output frequency of an output signal of the oscillator.
