Abstract
A power amplifier arrangement having a distributed antenna is disclosed. The power amplifier arrangement has two or more signal paths which are coupled to a common input. Each signal path has an amplifier with a downstream antenna. The respective signal paths with the antenna are activated or deactivated by a control device as a function of the desired gain or output power. This results in high efficiency over a wide frequency range. The polar diagrams of the antenna branches preferably correspond to those of a single antenna.
