Definitions

the present invention relates to an arrangement for connecting several transmitters and receivers assigned to different frequency channels to a common antenna with the aid of circulators connected in a chain.
Such an arrangement is e.g. known from DE-PS 26 41 875.
the invention is based on the object of specifying an arrangement of the type mentioned at the outset, which has a small-volume design and in which the transmitted message signals are attenuated as little as possible.
each according to the invention is a transmitter / receiver couple connected to a circulator arm each within a circulator chain connected to the antenna. This saves a considerable number of circulators compared to the prior art, which has a particularly advantageous effect on the space requirement of such an arrangement, for example used in directional radio stations.
the filter branching W1, ..., Wn has two frequency passbands, one of which is tuned to the frequency channel of the connected transmitter S1, ..., Sn and the other to the frequency channel of the connected receiver E1, ..., En . All other frequency channels from neighboring transmitter / receiver pairs are reflected at the filter junction.
a reception signal picked up by the antenna A and intended for the receiver E2 is first switched through from the first circulator Z1 to the last circulator Zn-1, then from the last circulator Zn -1 of the chain connected to the filter branch Wn of the last transmitter / receiver pair Sn / En, reflected on it and fed back to the last circulator Zn-1, which forwards it back to the penultimate circulator.
the received signal finally reaches Refle xions on all the filter branches that are not tuned to its frequency band, from the end of the circulator chain back to the crossover that is tuned to pass for the received signal frequency.
the arrangement of the invention can be easily supplemented by further transmitter / receiver pairs by inserting one or more circulators with transmitter / receiver pairs into the circulator chain. This does not change the principle that all signal transmission paths have the same number of circulator passes.
