Embodiment Construction
[0028] figure 1 A rough block diagram of a circuit arrangement for processing or influencing radio communication signals is shown. Rather, the exemplary embodiment is a circuit arrangement for attenuation compensation, such as can be used, for example, in connection with the operation of the radio device 10 for a hands-free system equipped with an external antenna 14 . The circuit arrangement compensates for the attenuation of the signal received by the terminal 10 or output by it in the signal path between the terminal 10 or the mobile radio device and the external antenna 14 . The components of the circuit arrangement shown are functional groups according to the invention. Accordingly, the functional group according to the invention basically comprises: a detection unit 1 for detecting a transmission signal of a mobile radio device 10 operated by means of a circuit arrangement; a plurality of switching devices 3, 5, 6, 7; in particular arranged at the antenna The multiplex...

The invention relates to a solution for connecting signal paths in a circuit arrangement with multiband capability for processing and / or influencing signals in radio communication, on the basis of which at least the transmission paths (8, 8') of a corresponding circuit arrangement are activated or deactivated on the basis of the presence of a transmitted signal from a terminal (10) which is operated with the circuit arrangement. According to the proposed method, the transmission paths (8, 8'), which are deactivated in a basic state of the circuit arrangement, are periodically checked in succession for the presence of a transmitted signal from the terminal (10) by virtue of a multiplexer (3), which is provided as a functional component of a detection unit (1) in the function group according to the invention, being switched through by a controller (4) for the purpose of sequentially scanning the transmission paths (8, 8') of the initially mentioned circuit arrangement for the presence of such a transmitted signal. If a transmitted signal is present, only that transmission path (8, 8') of the relevant circuit arrangement which is the right one or designed for the frequency band of said transmitted signal is activated and only this transmission path (8, 8') continues to be checked for the presence of a transmitted signal.
Description
technical field [0001] The invention relates to a method for switching signal branches of a circuit arrangement for processing and / or influencing signals of radio communications into active or inactive depending on the presence of a transmission signal of a communication terminal operated with the relevant circuit arrangement solution. The solution relates to a corresponding method and to a functional group designed for carrying out the method, said functional group being a direct component of the circuit arrangement with the signal branch to be converted or assigned to such a circuit in terms of circuit technology device. Background technique [0002] In circuit arrangements for processing and / or influencing signals for radio communication, depending on their design and their purpose of use, in many cases it is necessary in many cases to activate or deactivate different signals of the circuit arrangements involved, respectively, corresponding to the respective operating st...
