Abstract: The invention relates to a multi-band, multi-part circuit arrangement for compensating the attenuation of HF wireless signals in the signal paths between a transmitting and receiving device and an external antenna. The circuit arrangement comprises power amplifiers, receiving amplifiers, at least one splitter, at least one combiner, duplexers and frequency and/or band filters, HF switching means as well as a detector circuit for the detection of transmission signals from the transmitting and receiving device and for providing control signals for the HF switching means.

Abstract: The invention concerns a circuit arrangement for the operation of transmitting and receiving devices (T/R devices) at an antenna. A plurality of T/R devices can be operated for the most part without loss relative to the transmission and receiving powers and almost without mutual influencing of the signal branches of the devices by means of this circuit arrangement. For this purpose, circuit modules for compensation of attenuation (compensators) are disposed between the common antenna and each T/R device. All transmitting and receiving branches of the compensator are connected with the antenna by means of one interconnection unit. The transmitting branches are brought together via passive combiners with the interconnection of an isolator in each case, whereby the output power of their transmission amplifiers is increased in order to equilibrate the attenuation in the combiners.
