摘要： A system includes a first circulator, a second circulator connected to the first circulator and a load, a third circulator connected to the second circulator, and a filter connected between the first and third circulators. The filter modifies the phase and amplitude of a first signal from the first circulator to produce a modified first signal. The modified first signal amplitude may be equal to the amplitude of a second signal from the second circulator. The phase of the modified first signal is about 180 degrees out of phase with the second signal phase. The third circulator circulates the modified first signal towards the second circulator. The first signal comprises a coupled signal from the first circulator. The second signal comprises a signal reflected from the load and a coupled signal from the second circulator. The filter may be a passive network having lumped, distributed, and resistive elements.

In one implementation, the above resonance circulator/isolator includes a magnet, a spacer, a single ferrite element, a center conductor and a pole piece. The center conductor is sandwiched between the magnet and the single ferrite element with the spacer interposed between the magnet and the center conductor. The pole piece is coupled to the single ferrite element, such that the single ferrite element is sandwiched between the center conductor and the pole piece. Magnetic shielding is not necessary in particular implementations.

摘要： A transmission line comprising a multi-layer dielectric slab structure including: a dielectric substrate layer (30) having a thickness d.sub.s and permittivity .epsilon..sub.s ; a conductive ground plane (31) on the bottom surface of the dielectric substrate layer (30); a dielectric guiding layer (32) having a thickness h and permittivity .epsilon..sub.g, where .epsilon..sub.g >.epsilon..sub.s, attached to the top surface of dielectric substrate layer (30); at least one elongated and relatively narrow dielectric loading strip layer (33) having a width W, thickness d.sub.1, and permittivity .epsilon..sub.1, where .epsilon..sub.g >.epsilon..sub.1, attached to the top surface of the dielectric guiding layer (32); and a conductive coating (34) on the top surface of the dielectric loading strip layer (32). Such a structure permits single mode propagation over a relatively wide frequency band. Radiation losses due to coupling of the desired mode to the substrate modes and the conductors are furthermore reduced and the polarization of the dominant mode is such as to render said structure relatively insensitive to small deviations from parallelism among the different interfaces. This invention is directed to transitions and power couplers implemented in such a multi-layer dielectric slab structure.
