摘要：
This paper presents a model of active-integrated power amplifiers and antennas in a scanning array environment. The model links together load-pull data and unit-cell antenna simulations through a synthesized power combining and matching network to determine the active load reflection seen by the individual transistors. From this an estimate of the overall power-added efficiency, interconnect losses and radiated output power is calculated for a complete scan range at a given operating frequency. The model is intended to provide a fast, first-order indication of the most suitable technology choice and design strategy for a given operating frequency and transmit power requirement.
