Abstract: The system obtains SOH of a first component, where the SOH indicates a difference between a current state of the first component and a state of a rated new component. The system obtains historical use of the first component. Based on the SOH and the historical use, the system determines a future SOH of the first component. The system obtains an indication of a requested SOH of the first component. Based on the indication of the requested SOH and the future SOH of the first component, the system determines a first time indicating when the first component will need to be replaced. The system determines a second time indicating when the second component is available to replace the first component, where the second time occurs before the first time. The system requests a delivery of the second component when the second time is substantially close to the first time.

Abstract: A hybrid network is disclosed having at least one hybrid coupler, and a plurality of circulators, each circulator having a first port connected to the hybrid network, and further having a second port and a third port. Each circulator is arranged to direct a signal received via the second port to the hybrid network via the first port, and to direct a signal received from the hybrid network towards the third port.
