Abstract
System including a dual-fed antenna element is designed to present 2×2 port impedances that guarantee high efficiency operation of the main- and auxiliary transistors at peak- and backed off power. The proposed solution eliminates the need for lossy power combining, such as PCB based circuit combining or impedance matching networks between the antenna element and the main- and auxiliary amplifiers. The power from the main- and auxiliary transistors are combined at the circuit level by the antenna element.
