Abstract: The present invention discloses a low-field assembled isolator, which includes a rectangular body, wherein the body includes an upper cavity and a lower cavity which are connected in a stacked manner; gaps are formed in four side surfaces of the body through the joint surfaces of the upper cavity and the lower cavity respectively; and the isolator further includes a U-shaped magnetic circuit cover plate and two L-shaped magnetic circuit baffles; and the two L-shaped magnetic circuit baffles are respectively disposed at two corners, away from the vertical plate, of the body so as to seal the joint between two adjacent gaps. The gaps at the joint of the upper cavity and the lower cavity are effectively and fully sealed, thereby effectively preventing signal leakage and improving the performance of the low-field assembled isolator.

Abstract: A high-efficiency integrated circulator/isolator includes a hollow base having an opening formed in the top, a coupler, a first resistor, and an SMP signal connector, wherein three notches are formed in the peripheral wall of the base, support bases are respectively arranged at the bottoms of the notches, and a laminated assembly is arranged in the base and includes a central conductor; and the coupler, first resistor, and SMP signal connector are respectively arranged on the support bases, the coupler has an output terminal electrically connected to an input terminal of the central conductor as well as a coupling terminal electrically connected to an external monitoring system, and the central conductor has an output terminal electrically connected to an input terminal of the SMP connector as well as an isolation terminal electrically connected to the first resistor. The circulator/isolator is integrated to a greater degree and is smaller in size.

Abstract: A subminiature circulator includes feed pin assemblies, a hollow base having an opening formed in the top, and a locating iron sheet, wherein a laminated assembly is arranged in the base, notches are formed in the peripheral wall of the base and are communicated with the bottom face of the base, the locating iron sheet is clamped in the laminated assembly and is provided with extension parts which stretch out of the base via the notches, and the feed pin assemblies are installed in installation holes formed in the extension parts. The feed pin assemblies are arranged in the installation holes formed in the extension parts of the locating iron sheet, and such installation manner is not limited to an integrally-formed structure, so that a sophisticated device is easy to machine in the fabrication process.
