Abstract
The present disclosure includes techniques for combining signal power. In one embodiment, a plurality of power amplifiers generate amplified signals. A plurality of first transmission lines are electrically coupled outputs of the power amplifiers. Second transmission lines 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 to a node. The amplified signals are added at the node. The node is coupled to an antenna terminal.
