Problems solved by technology

[0003] At present, traditional circulators usually use manual soldering or gold wire bonding to electrically connect the pins to the circuit on the PCB, which is not only inefficient, but also unable to meet the requirements of high integration.
Although the structural design of existing circulators uses surface mount technology (SMT: Surface Mount Technology), it is impossible to achieve true miniaturization by simply adjusting the electrical connection between layers.

Abstract

The invention discloses a microstrip circulator, which can be applied to isolators and microwave communication and is particularly used in a large scale in T / R assemblies. A gyromagnetic layer of themicrostrip circulator comprises a first substrate and a gyromagnetic body embedded in the first substrate, wherein the dielectric constant of the first substrate is higher than that of the gyromagnetic body. Due to the fact that the gyromagnetic layer adopts the composite structure, the dielectric constant can be improved on the whole. Under the same performance requirements as the products in theprior art, the microstrip circulator can reduce the area of a central conductor, then the area of the whole microstrip circulator is reduced, and miniaturization in the real sense is achieved.

Description

technical field [0001] The invention belongs to the technical field of circulator design and manufacture, and in particular relates to a microstrip circulator, an isolator and a T / R assembly using the microstrip circulator. Background technique [0002] The circulator is a non-reciprocal device with several terminals, which includes a gyromagnetic material made of gyromagnetic material. Due to the combined action of an external microwave magnetic field and a constant DC magnetic field, the gyromagnetic material produces gyromagnetic properties, so that the gyromagnetic material propagating in the gyromagnetic Electromagnetic waves are polarized and rotated to achieve one-way transmission of high-frequency signal energy. Therefore, gyromagnetic materials are widely used in the field of microwave communications. With the development of communication technology, the requirements for circulators are getting higher and higher, for example, the circulators are required to be small...
