Abstract:
1. A base station for a wireless cellular communication network, comprising: a first and a second radio frequency unit, a first transmission line for transmitting a first component of a differential signal from the first radio frequency unit to the second radio frequency unit, a second transmission line for transmitting a second component of a differential signal from the first radio frequency unit to the second radio frequency unit, first coupling means for coupling out a signal of the first transmission line, the first coupling means having first electrical properties having a first impact on the transmission of the first component, said first coupling means comprising a first coupling module coupled to a detector, second coupling means being adapted to be coupled to the second transmission line, second coupling means having second electrical properties having a second impact on the transmission of the second component, the first and second electrical properties being substantially equal such that the first impact and the second impact are substantially equal, characterized in that the second coupling means comprises a termination element and a second coupling module that couples a second coupled signal out of the second transmission line to the termination element, said termination element terminating the second coupled signal.
