ABSTRACT:
The present invention relates to a method and an apparatus (20) for a radio frequency component (10), RF component, for use in antenna systems, wherein the RF component (10) is adapted to guide direct current, DC, power signals; control signals and RF signals, and wherein the RF component (10) is adapted to separate the DC power signals and the control signals from the RF signals. The apparatus according to the present invention comprises an impedance matching network interface (21) adapted to match at least one control signal of the separated control signals to at least one predetermined impedance value; and a DC and signalling controller (22) that is adapted to control, along DC paths, the DC power signals to at least a first port of the RF component (10), and adapted to control, along signalling paths, the control signals to at least a second port of the RF component (10), whereby the DC power signals and the control signals are controlled independently of each other. The present invention also relates to a radio frequency component that comprises an internal and/or an external interface used to connect the apparatus (10).
