Реферат: The present disclosure includes techniques for combining signal power. In one embodiment, a plurality of power amplifiers (101-104) generate amplified signals. A plurality of first transmission lines are electrically coupled to outputs of the power amplifiers (101-104). Second tramsmission lines (111-114) are magnetically coupled to the first transmission lines to receive the amplified signals. The amplified signals propagate down the second transmission lines to a central conductive region (110) to a node (151). The amplified signals are addedat the node. The node is coupled to an antenna terminal (150). Embodiments show the second transmission lines (111-114) and the central conductive region 8110) forming a radial combiner/splitter. They show further differential power amplifiers (101-104) having strip line baluns composed of the first and second transmission lines ( 111-114).
