Dielectric Resonator/Coaxial Resonator

 

TE01δ Mode Resonators (DR Pack)       

  • D-40 material can obtain very high Q value in a frequency band of the base station.(Qu=25000@2GHz)
  • D-24 can obtain a high Q value also in the 60GHz millimeter wave band.
  • Resonant frequency is up to 60GHz from 260MHz.
  • Support base can be made of alumina, forsterite, quartz, etc.

TEM Mode Resonator (for VCO)

Coaxial Resonator

  • Outer diameter size is 1.55mm □ ~ 18mm □, φ16 ~ φ50. The length is 5 times the diameter's (The maximum length is 100mm). (OD×5≒MAX L)
  • Resonance frequency range: 140MH ~ 7000MHz
  • Various package options available; bulk packagingtray, taping and so on.
  • Standard materials are D-9, D-21, D-38 and D-90N. Please contact us for the other materials.
  • Silver metallization by dipping can adjust the thickness from 5μm to 40μm.

Tab-less Type Coaxial Resonator

Advantages to use tab-less resonator.
  • No metal tab is needed.
  • Suitable for SMT.
  • Large foot print makes reliable connection.
  • No need to adjust tabs.
  • You can expect higher Q.

Coaxial Resonator with Tab

  • We can produce the resonator with tabs.
  • The size can be from 2mm□ to 18mm□.
  • Etching process enables the shapes you would like.

SIR Type 

  • It is possible to reduce the length by step impedance structure.
  • The step impedance structure reduces the resonator length up to 40%.
  • Quarter type size: 1.8mm □ ~ 18mm □, Cozxial big type size φ16 ~ φ50 are also available.
  • Minimum Frequency: 60MHz -
