Problems solved by technology

[0003] The difficulty of miniaturization of microwave gyromagnetic circulator is that miniaturization will affect the bandwidth of the device
The size of existing circulators for base stations is concentrated in 10mm and 7mm, which is large in size and high in cost. In addition, the central conductor and the dielectric ferrule in the miniaturized microwave gyromagnetic circulator are often connected by direct contact. The stability is difficult to guarantee, and the central conductor and the dielectric ferrule are prone to disconnection and conduction

Abstract

The invention relates to a super-miniature microwave gyromagnetic circulator, which comprises a shell, and a first ceramic ring ferrite, a central conductor, a second ceramic ring ferrite and a medium insertion core which are arranged in the shell. The medium insertion core comprises an insertion pin, and the foot part of the central conductor is provided with a through hole matched with the insertion pin. The dielectric constant of the first ceramic ring ferrite and the dielectric constant of the second ceramic ring ferrite are respectively greater than or equal to 30; the first ferrite and the second ferrite are respectively BiCaVIG ferrite; the pin comprises an extending part and a fixing part which are connected, the diameter of the extending part is smaller than that of the fixing part, the fixing part is fixed on the connecting seat, the pin and the foot part are welded at the through hole through solder paste, and a tin containing groove is formed in the connecting position of the extending part and the fixing part. According to the microwave gyromagnetic circulator, miniaturization can be realized under the condition that the bandwidth is not reduced; and the central conductor is welded with the contact pin and the tin containing groove is arranged on the contact pin, so that the structural stability and the conduction stability of the microwave gyromagnetic circulator are improved.

Description

technical field [0001] The invention relates to the technical field of microwave ferrite devices, in particular to an ultra-miniature microwave gyromagnetic circulator. Background technique [0002] Embedded isolators are widely used in the era of 2G / 3G / 4G and the Internet of Things, including that the future 5G is getting closer and closer to us. According to relevant reports, China's 5G is expected to be commercially available in 2020. The Internet of Things, smart home appliances, and unmanned With the realization of driving and other technologies, mobile data traffic will increase by 8 times, and 5G users are expected to exceed 1 billion. Because of the sharp increase in the number, upstream customers have put forward very strict requirements for cost control, miniaturization and mass production of isolator manufacturers. [0003] The difficulty of miniaturization of microwave gyromagnetic circulator is that miniaturization will affect the bandwidth of the device. The s...
