摘要： A radar transceiver chip for transmitting a transmission signal and for receiving a received signal is proposed. The radar transceiver chip includes a transmitting branch, a receiving branch, a coupler, by means of which the transmitting branch is coupled to the receiving branch, and exactly one antenna terminal for connecting an external antenna to the radar transceiver chip. The coupler is coupled to the antenna terminal and is configured to output at least a portion of the transmission signal to the antenna terminal and to feed at least a portion of the received signal, received via the antenna terminal, into the receiving branch, the receiving branch comprising a receiving mixer which is configured to generate an intermediate frequency signal on the basis of the received signal.

摘要： A radar fill level measurement device includes a radar sensor unit which has comprising a radar antenna emitting a measurement signal towards a filling material surface. The radar fill level measurement device in addition includes a limit level sensor unit determining a fill level of the filling material. The limit level sensor unit detects when the spacing between the filling material surface and the radar antenna falls below a minimum spacing. A radar antenna arrangement is for a radar fill level measurement device. The radar antenna arrangement includes a radar antenna horn which has a housing and/or a cover, and a limit level sensor unit. At least part of the limit level sensor unit is arranged on the housing or on the cover or is integrated therein.

摘要： Level measuring device which can compensate the distortions, caused by an STC filter, of the received signal, by measuring a reference signal which passes through the receiving branch and also through the STC filter, during the ongoing operation of the level measuring device or during manufacture. For example, after passing through the receiving branch, this reference signal can be fed to a microprocessor which can calculate the correction values of the IF signal therefrom. A switch can be provided which can switch over between the reference signal and the IF signal.
