Claim 0:
1. Method of operating a power combiner network (1), the power combiner network (1) comprising a power combiner device (10) having N secondary ports (11(1, 2, . . . , N)) combining into one primary port (12), wherein respective N secondary port (11(1, 2, N)) is provided with a phase shifter arrangement (13), wherein respective phase shifter arrangement (13) is configured to set a phase of a signal fed through respective N secondary port (11(1, 2, . . . , N)), and a load control arrangement (14), wherein respective load control arrangement (14) is configured to set the N secondary ports (11(1, 2, . . . , N)) in an active or in an inactive operation mode, and for I inactive secondary ports (11(1, 2, . . . , N)) which are set in inactive operation mode the load control arrangement (14) is further configured to set a phase of the signal reflected from the I inactive secondary ports (11(1, 2, . . . , N)), wherein the method comprises the method steps of;
step A (100), selecting which of the N secondary ports (11(1, 2, . . . , N)) that should be set in an inactive operation mode, thereby being I inactive secondary ports (11(1)), and which of the N secondary ports (11(1, 2, . . . , N)) that should be set in an active operation mode, thereby being A active secondary ports (11(2)),
step B (110), setting selected I inactive secondary ports (11(1, 2, . . . , N)) in an inactive operation mode by means of the load control arrangement (14),
step C (120), retrieving a phase required for respective I inactive secondary port (11(1)) and retrieving a phase required for respective A active secondary port (11(2)) in order for respective A active secondary port (11(2)) to minimize the reflected signal from the power combiner device (10) and provide desired power to the primary port (12),
step D (130), setting the phase value of respective load control arrangement (14) for respective I inactive secondary port (11(1)) according to respective retrieved phase, and
step E (140), setting the phase value of respective phase shifter arrangement (13) for respective A active secondary port (11(2)) according to respective retrieved phase.
