TOKEN DR Dielectric Coaxial Ceramic Resonators Dielectric Coaxial Ceramic Resonators Token Ceramic Coaxial Resonators (DR) Is The Cornerstone of RF Microwave Communications Preview Dielectric ceramic resonator is a kind of microwave components, also known as coaxial resonator, Token electronics manufacturing dielectric resonator (cylindrical, ring), coaxial resonator (rectangular cavity, cylindrical cavity, coaxial cavity resonator), microwave resonator, etc. It is made high-Q dielectric ceramics, temperature coefficient is good, mainly used in microwave oscillators and filters. Dielectric resonator size and dielectric material is inversely proportional to the square root of the dielectric constant, dielectric materials, dielectric constant the greater the required dielectric ceramic block the smaller, thus the smaller the resonator size. Another important parameter is the insertion loss, low dielectric loss microwave dielectric materials, dielectric filters that affect the insertion loss of a major factor. Microwave dielectric Q value and dielectric loss is inversely proportional to the relationship. Q value is greater the lower the filter insertion loss. Therefore, the microwave dielectric ceramic materials of high dielectric constant is conducive to the miniaturization of microwave dielectric filters, can filter with the microwave tube, a microstrip line realization of microwave hybrid integrated circuit, so that the device dimensions to mm order of magnitude, the price is also much lower than the metallic cavity. The coaxial resonator impedance used in TEM mode is direct function of its dimensions and of the dielectric material permittivity. Token coaxial ceramic resonators provide the customers with high Q higher parellel resonant impedance and better temperature characteristics than inductor coils and associated lumped constant elements used in RF amplifiers and oscillators circuits. According to dielectric resonator frequency stabilization mechanism, using dielectric resonator stabilized FET oscillator frequency (also referred to DRO) can be classified into 4 types, namely, reflective, band-reject type, transmission type and feedback type. Coaxial Resonator named by the internal and external, between the inner and outer conductor filling a variety of dielectric ceramics to be dielectric ceramic coaxial resonator name. It is longer than the length of the unfilled resonator is much smaller. Coaxial resonator with two ports, depending on port different boundary conditions, in accordance with the basic structure of the resonator is divided into three types: half-wavelength type, quarterwavelength type, and capacitive load type, each structure each with distinct characteristics.
