Device for routing (1) in terms of frequency between a first channel (2) and at least two second channels (10, 20), each including a filter (13, 23) transmitting a frequency band specific to the second channel (10, 20), having a circuit (14, 24) blocking the frequency band of the other second channel (10, 20), these filters (13, 23) being linked to the first channel (2) via a specific line (12, 22) amplifying more the impedance of the tuned filter (13, 23) for the frequency band of the other second channel (20, 10) than it does for the frequency band of the second channel in question (10, 20). Application to radiotelephone diplexers. <IMAGE>
