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).

N-port junction device for processing modulated digital RF signals, n being an integer larger than three, the n-port junction device comprising:
- at least 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 at least 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 one output port (6, 7) and each output port (7, 7) is connected to a power sensor (P1, P2).
Method for processing modulated digital RF signals, comprising the following steps:
- supplying two input ports (4, 5) of a n-port junction device respectively with RF signals, one of the RF signals being the modulated digital RF signal to be processed and n being an integer larger than three,
- wherein the n-port junction device comprises two passive signal combining means (2, 3) connected to each other and respectively one of the passive signal combining means (2, 3) is connected to one of the input ports (4, 5), and
- supplying at least one output signal from each of the passive signal combining means (2, 3) to a power sensor (P1, P2).
