Aging : Ceramics aging is small. Microwave Dielectric Ceramics any change in resonant frequency can be attributed to changes in measurement cavity or measurement techniques. 2. Water Absorbing : Ceramics absorb water is not obvious, but the moisture condensation in the ceramic microwave dielectric resonator on the surface will affect the Qu. But Qu will be self-healing, when the water dried, For example, Dielectric resonator in the filter operation of the self-heating. 3. Cleanliness : Qu degradation of the oil may be due to a finger, pencil lead note, tape, adhesives, or other contaminants. Cleanliness of the dielectric ceramics is important.

Dielectric Constant : In fact, the microwave dielectric ceramics of the dielectric constant is not fixed. It varies with the additives added, and used to determine the temperature coefficient ceramics. The dielectric constant of each batch is slightly different and it changes slightly with temperature changes. Token compensates for these effects and provide dielectric resonators size to frequency, and offers custom temperature coefficient on request. 5. Dielectric loss factor tanδ & Qu : Dielectric loss factor and quality factor of the relationship, such as Quality Factor (Q = 1 / tanδ), Dielectric microwave materials are commonly assigned a loss tangent to permit an estimate of signal losses. Ceramic dielectric resonator is usually run on a specific frequency, a specific geometric shape, it can directly measure its size, with no-load quality factor Qu, Qu is an important basic resonator parameters (more useful than the loss tangent), particularly suitable filter and oscillator applications. 6. Smooth Surfaces : Ceramic hard surface contact, it is prone to very small fragments. Most of the small fragments will not affect the electrical properties of dielectric ceramics. Ceramic surface roughness is not particularly important factor. Ceramic dielectric resonator itself does not current exist only in the form of stored energy from the field. Smooth surfaces are desirable from the standpoint of avoiding trapped contaminants. 7. Thermal Shock : Microwave dielectric ceramics in the temperature exceeds 1200° in furnace to burn out, they can be more resistant than the temperature of electronic devices, far beyond the welding temperature. However, the thermal conduction velocity of dielectric ceramics is much slower than the metal. Large temperature gradient through the ceramic device, because of uneven expansion, could lead to device failure, which is called thermal shock. Suddenly applied heat in the thick ceramic devices will lead to broken ceramics. 8. Adhesives : Adhesives to install ceramic dielectric resonators must be carefully selected. Adhesives will reduce the dielectric ceramics Q u, The right adhesives can reduce Qu to a minimum, while ensuring the adhesion strength. TOKEN
