Abstract
The present invention relates to n-port junction devices for processing modulated digital RF signals, n being an integer larger than 3, the n-port junction device comprising two RF input ports (4, 5), two passive signal-combining means (2, 3) connected to each other wherein respectively one of the passive signal-combining means (2, 3) is connected to one of the RF inputs (4, 5), and at least two power sensors (P1, P2) wherein each of the passive signal-combining means (2, 3) has at least an output port (6, 7) and each output port (6, 7) is connected to a power sensor (P1, P2). The two passive signal-combining means (2, 3) are connected with each other by means of a phase shifting element (10).
