The combiner comprises N coaxial cables configured to be connected to respective outputs of the N radio frequency power amplifiers, where N is an integer greater than one. Each N coaxial cable is configured to receive an amplified radio frequency signal from each one of the N radio frequency power amplifiers. The board contains capacitances and is configured to be connected to each N coaxial cable and combines radio frequency signals. N coaxial cables and capacitances provide N inductance and capacitance combinations. The connector is configured to connect the output of the board to the load.
