Power amplifier arrangement with antennas e.g. for transmission paths in mobile RF appliances, has signal paths each coupled to input and each comprising amplifier

摘要

A power amplifier arrangement with antennas, has a first signal path (13,26) coupled to the input (1) and comprising a first amplifier (13), a first antenna (26) in the first signal path (13,26) is coupled to the output of the first amplifier (13), a second signal path (15,28) is coupled to the input (1) and comprises a second amplifier (15), a second antenna (28) in the second signal path (15,28) is coupled to the output of the amplifier (15) and a control device is coupled to the first- and second signal paths for activating and deactivating the first and second amplifiers, depending on the required amplification. Independent claims are included for the following: (A) Application of a power amplifier arrangement.(B) Method for amplifying and radiating a signal.
