Abstract
The disclosure relates to a circuit arrangement for transmitting uplink and downlink signals between at least one terminal device and at least one antenna, wherein the circuit arrangement comprises a signal coupler for providing a decoupled uplink or downlink signal, a device for providing a reference signal of adjustable frequency, a mixer for mixing the decoupled signal and the reference signal and a filter device for low-pass or bandpass filtering of the mixed signal, wherein the circuit arrangement comprises an evaluation device for evaluating the filtered signal, wherein, depending on the adjusted frequency of the reference signal and on at least one signal property of the filtered signal, a frequency band or channel in which the transmitted signal is being transmitted can be identified, and also to a method for identifying a frequency band or channel.
