 DR20
Product Introduction
Token coaxial resonators (DR) are the cornerstone of RF
microwave communications.
Features :
High quality factor.
High dielectric constant.
Low temperature coefficient.
Wide range of resonant frequency.
Applications :
CDMA/PCS/WLL/IMT2000.
Filters, Duplexer, Oscillators (DRO/VCO).
Wireless headphone, wireless security system.
900MHz, 1.8GHz, 2.4GHz, 5.8GHz wireless phone.
(DR) is a kind of microwave components, also known as ceramic
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 micro strip 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 (DR) 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
parallel 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.
(DR) series 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, quarter-wavelength
type, and capacitive load type, each structure each with distinct characteristics. Token (DR) series
features with small size, high temperature stability characteristics. Indirectly, (DR) series is suitable for
a variety of microwave communications equipment, particularly suitable for PCS / PCN filters, base
stations, radar detectors, satellite broadcast reception systems, military microwave facilities. Comply
with RoHS standards.
Custom parts are available on request. Token will also produce devices outside these specifications to
