CERAMIC COAXIAL RESONATORS
General characteristics
εr = 90
DIMENSIONS AND CONFIGURATIONS
The TEMEX coaxial resonators are available over a frequency range of 300 MHz to 6 GHz with four
preferred square cross section sizes, having side length of 2, 4, 6 and 12 mm.
Other square section dimensions 3, 8 and 10 mm (S) information can be obtained upon request.
Table 1 summarizes the choice of sizes and dielectric materials available.
The length of the component (L) can be determined from the chosen frequency (F) and dielectric
constant (
εr) as follows:
λo

√ εr

IMPEDANCE Z
The coaxial resonator impedance used in TEM mode is a direct function of its dimensions
and of the dielectric material permittivity.
Table 2 indicates for each standard side length, and for each dielectric constant, the impedance value,
independent of the resonator length
