Abstract
An N-way power combiner includes a common output port and N input ports, each adapted to be connected to an RF input signal source. N load ports are provided with each being adapted to be connected to a reject load. N first transmission lines are provided with each connected at one end to the common output port and each connected at its opposite end to a respective one of the N input ports. N Second transmission lines respectively interconnect each of the input ports with one of the load ports. Also, N third transmission lines are provided and wherein each connects a respective one of the load ports with a common point. N reject loads are provided with each connected to a different one of the N load ports for dissipating power in the event that one or more of the RF input signal sources is deactivated. A common heat sink is coupled to all of the N reject ports with the heat sink being sized and configured to provide a total heat dissipation capability to dissipate more than the maximum amount of heat required to be dissipated by any one of the N reject loads and less than N times that amount.
