Abstract

An improved device for receiving and transmitting mobile telephony signals comprises at least 4 channels. Each of the at least 4 channels (K1, K2, K3, K4) can be controlled with a transmission signal, that is different from the other channels, which can be generated with a separate channel module (KM1, KM2, KM3, KM4) from various data streams. A controller device is provided for, via which several or all of the power amplifiers, which are connected in several or all channels (K; K1, K2, K3, K4), can be operated in-phase or phase-locked with each other, in such a way that the transmission signals (TX) amplified in the channels concerned (K; K1, K2, K3, K4) can be synchronized and interconnected. As a result, a transmission signal can be radiated with a higher transmission power.
