Abstract
A microwave measuring device having a transmitting module and a receiving module and an apparatus having these modules are described. The two modules are accommodated either in a common housing or in separate housings. The transmitting module can be coupled to a transmitting antenna and the receiving module can be coupled to a receiving antenna. In order to compensate for measurement errors, in particular temperature-related measurement errors, at least one RF bypass cable runs outside the housing/the housings and can be used to couple the transmitting module and the receiving module while bridging the measuring section defined by the two antennas.
