Abstract
The invention relates to a transmitter combiner arrangement, and more specifically a transmitter combiner arrangement usable in communication systems transmitting signals with a wide dynamic range, e.g. in a base station of a multilobe telecommunication system having phased array antennas. The transmitter arrangement according to the invention enables amplification of low and high levels with high efficiency by means of a hybride arrangement comprising a hybride of progressively coupled single carrier power amplifiers (SCPA) and a multicarrier power amplifier (MCPA) connected with a combiner network.
