ABSTRACT:
A high power Gysel multinode power network for an RF signal, having a plurality of RF ports, a plurality of RF isolation loads, each load being connected through a coaxial transmission line to a respective RF port, a combined port, comprising a first hub having a plurality of first radiating arms, each radiating arm comprising a coaxial transmission line extending to one of said RF ports, a node, comprising a second hub having a plurality of second radiating arms, each radiating arm comprising a coaxial transmission line extending to one of said RF isolation loads; and a common heat sink for dissipating heat from said plurality of RF isolation loads. The network is formed such that a normalized phase difference of the RF signal at a design frequency through said coaxial transmission line between each of said RF ports and said combined port is approximately equal to zero with respect to a portion of the RF signal traveling through said transmission line between each of said RF ports and a respective RF isolation load, through said transmission line between each of said RF isolation loads and said node, and through all other paths between said node and said combined port.
