Comparing with microwave dielectric components made of Token's
ceramic materials and metal cavity resonator, obviously, Token dielectric resonator features with a
light weight, small volume, temperature coefficient of stability, cheap, and so on. They have been
widely used in satellite broadcast reception systems, PCS / PCN filters, base stations, radar detectors,

microwave, modern medicine and many other areas.
Taking advantage of Token's microwave dielectric ceramic materials for dielectric filters and
resonators, with a relatively high dielectric constant, can make the device smaller, space-saving design
of the circuit; high quality factor Q value and low dielectric loss, in order to ensure a good selection
frequency characteristics and low insertion loss of the device; the temperature coefficient is small, in
order to ensure the thermal stability of the device. Dielectric constant, quality factor Q, the temperature
coefficient, these three parameters to evaluate the important microwave dielectric ceramic material
specifications and production.
Custom parts are available on request. Token will also produce devices outside these specifications to
meet specific customer requirements, contact us with your specific needs. For more information,

Application Notice
Application Notice TE01δ Mode (TE)
1. 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
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.
4. 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 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 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 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 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.

General Information
Advantage of Token's Microwave Dielectric Components
New Microwave Dielectric Materials for Wireless Communication from Token Electronics
"Everything from the electromagnetic properties to microstructure of the material is important for the
final result"
A small ceramic component made from a dielectric material is fundamental to the operation of filters
and oscillators in several microwave systems, such as satellite TV receivers, military radar systems,
Global Positioning System (GPS) devices, and mobile communications. Token Electronics had been
able to develop specialized piezoelectric materials which lead to more reliable and clearer microwave
communication signals.
In microwave communications, dielectric components are used to discriminate between wanted and
unwanted signal frequencies in the transmitted and received signal. When the wanted frequency is
extracted and detected it is necessary to maintain a strong signal nevertheless. For clarity it is also
critical that the wanted signal frequencies are not affected by seasonal temperature changes.
The resonator materials for practical applications have to have certain key properties. A high relative
dielectric constant is needed so that the materials can be miniaturized and a high quality factor (Q) is
needed for improved selectivity. Low temperature variation of the material’s resonant frequency is also
required so that the microwave circuits remain stable.
Although large numbers of ceramic dielectric materials have been developed, it has proven difficult to
satisfy all these requirements in a single material at a reasonable cost. "Token takes the advantages of
these new materials that they are relatively cheap compared with some of the compounds currently
used and in the future they can be improved even further by suitable additives and by optimizing the
preparation conditions."
Dielectric Material Composition & Study
The new dielectric materials developed by Token, are based on ceramics formed by baking the pressed
powdered starting material mixture in a furnace at between 1200 and 1550 degrees Celsius.
Token Engineers used X-ray diffraction studies, Raman spectroscopy and scanning electron
microscopy to reveal the structure of the ceramics. The materials have the general formula Ce
(M1/2Ti1/2) O3.5. Ce is the element cerium, Ti is titanium and O is oxygen. "M" represents any one of
the metals magnesium, zinc, calcium, cobalt, manganese, nickel or tungsten. The numbers refer to the
proportions of each element in the ceramic.
"Further work is in progress to find the exact composition, internal structure and secondary phases in
the ceramics".
