A recently granted patent (Publication Number: US11962059B2) discloses a method for operating a power combiner network with a power combiner device having multiple secondary ports combining into one primary port. Each secondary port is equipped with a phase shifter arrangement and a load control arrangement to set the ports in active or inactive modes. The method involves selecting inactive and active secondary ports, setting the inactive ports, retrieving required phases for active and inactive ports to minimize reflected signals, and adjusting phase values accordingly. Additionally, the method includes sub-methods for determining port combinations for desired output power, detecting failed amplifier devices, accessing reference databases for phase requirements, and calculating required phases.

Furthermore, the patent describes a power combiner network configuration where each secondary port includes an amplifier device, with the method involving detecting amplifier failures and setting inactive ports accordingly. The network also features a load control arrangement with a switch and phase shifting device, along with phase shifter arrangements between the power combiner device and amplifier devices. The patent covers a computer program and computer-readable medium for executing the method steps, as well as a control unit designed to control the power combiner network operation based on the disclosed method.
