Industry frontier: 5G era is the development era of ceramics

The field of information technology has become an important power engine to enhance the strength of national scientific and technological innovation, promote economic and social development and improve overall competition. 5G is a new generation of basic productivity that opens a new era of industrial digitalization and the Internet of Things. Countries around the world to seize the highest point of 5G communication technology as an important strategy for national development, whether in key components, upstream material preparation or network deployment and other aspects have begun to actively layout, pre-emptive development opportunities.

Overview of Microwave Ceramics

There are three main bases for characterizing the properties of microwave ceramics, namely, the relative dielectric constant (εr), the quality factor (Q×f), and the temperature coefficient of resonant frequency (τf)[23].

Microwave dielectric ceramic materials and their industrial development and future prospects

Nowadays, microwave dielectric ceramics are widely used in various modern communication devices and become the key material for manufacturing microwave dielectric filters and resonators. With the rapid development of related fields,

Fundamentals of RF Microwave Circuits

The so-called microwave circuit, usually refers to the working band of the wavelength of 10m ~ 1cm (that is, 30MHz ~ 30GHz) between the circuit. In addition, there are millimeter waves (30 to 300GHz) and submillimeter waves (150 to 3000GHz). In fact, circuits with higher operating frequencies are often referred to as "high-frequency circuits" or "radio frequency (RF) circuits. Due to the high operating frequency of microwave circuits, compared with general low-frequency circuits and digital circuits in terms of materials, structures, circuit forms, components and design methods,

The application of RF microwave circuit

According to Maxwell's electromagnetic field theory: an oscillating electric field produces an oscillating magnetic field, and an oscillating magnetic field produces an oscillating electric field.
