Abstract
A radio-frequency circuit has a signal processing unit for processing a symmetrical input signal, two signal inputs for receiving the symmetrical input signal, a connection which is used as a ground point for the symmetrical signal, and a line which connects the signal inputs and has a length which essentially corresponds to an odd-numbered multiple of half the wavelength of the input signal. A method for testing a radio-frequency circuit having a signal processing unit for processing a symmetrical input signal is additionally provided.
