摘要： A radio frequency combining system is disclosed that uses commercially available quadrature hybrid couplers configured in a unique manner to combine any radio frequency sources such as transmitters into a single load such as an antenna. The radio frequency combining system is bidirectional and can be used in the receive mode to combine the output of a receive antenna with outputs from an interference canceller to then supply received signals to a multiple receiver system.

摘要： An apparatus for doubling the amount of power that can be safely applied to a circulator-based isolator, which is made up of an input hybrid which receives an RF signal and outputs two divided RF signals, a Y-junction circulator that receives one of the divided RF signals at one of the circulator ports and outputs it at another circulator port, an output hybrid which receives the two divided RF signals, combines them, and sends them on, the output hybrid simultaneously receiving a returned signal, dividing it, and outputting two divided returned signals, one divided returned signal going to the circulator and the other divided returned signal going directly to the input hybrid, a phase retarding circuit which takes the half of the divided returned signal that went back to the circulator and retards its phase by 180 degrees and sends it back to the circulator, where it goes to the input hybrid as well, to be recombined with the other half of the returned signal and attenuated.
