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,

Microwave Dielectric Resonator Advantages

As is well known, the way to achieve miniaturization, high stability and low cost of microwave equipment is the integration of microwave circuits. In the process of microwave circuit integration, the metal waveguide realizes the integration of planar microstrip, and the microwave tube realizes the miniaturization. However, due to the large volume and weight of various metal resonant cavities in microwave circuits,

Use of Dielectric Resonator

Microwave dielectric ceramics are mainly used as resonators, filters, dielectric antennas, dielectric guided wave circuits and other microwave components. The advantages of microwave dielectric filter are miniaturization, low loss, low frequency temperature coefficient, high dielectric constant and low cost. Compared with the metal resonator filter, it has the advantage of miniaturization, and its volume is only a few tenths of the former; compared with the acoustic surface filter, it uses high frequency and low cost.
