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 so-called microwave circuit, usually refers to the working band of the wavelength of 10m ~ 1cm (that is, 30MHz ~ 30GHz) between the circuit.

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, there are many differences and many unique places in terms of materials, structures, circuit forms, components, and design methods compared with general low-frequency circuits and digital circuits. As an independent professional field, microwave circuit technology has developed very mature in theory, materials, technology, components, and design technology, and has been applied more and more widely.

In addition, with the rapid development of large-scale integrated circuit technology, the current operating speed of the chip has exceeded 1GHz. In the design of chips, packages and application circuits of these high-speed circuits, some microwave circuit design techniques have also been fully applied. In the past, the boundaries between the traditional low-frequency circuits and digital circuits and microwave circuits will become more and more blurred, and there will be more and more technical applications for mutual reference and integration.
