Innovations brought by 5G technology would have more impacts on our daily life in the Post-epidemic Period, include intelligent security, self-driving technology, VR/AR, and telemedicine, thus it could be argued that 5G technology are becoming an important engine for national economy development and social informatization. Besides 5G Samarium Cobalt magnets, 5G microwave ferrite has also attracted lots of attention.

Ultra-dense Networks (UDN) is a key technology to enhance data flow of future 5G network. The realization of UDN technology must massively increase the number of 5G base stations. 5G base station utilizes a large number of isolators and circulators. Each amplifier in base station amplifier contains several isolators to ensure mismatch protection.

Isolator and circulator in 5G base station need to satisfy low volume and loss. Its consistency of performance, temperature stability, and power durability should be more ideal in the meanwhile. As the core component of isolator and circulator, 5G microwave ferrite, also known as garnet, need to have low electromagnetic loss, relatively higher Curie Temperature and consistency of performance. The massive growth of 5G base station is also accelerating a huge rise of isolator and circulator. Then correspondingly, demand for 5G microwave ferrite has increased geometrically in the last two years.
