DIELECTRIC RESONATORS

Dielectric Resonators

TEM Mode DR

Tokenchina's Dielectric Resonators are optimal for human presence detection sensor. Compactness and high performance are achieved through dielectric ceramic technology and copper electrode plating technology. Compatible to Murata Dielectric Resonators DRR Series.


Features

  • Temperature-compensated dielectric constant stabilizes microwave oscillators
  • A variety of shapes are available for custom application requirements
  • High dielectric constant reduces the size of microwave devices
  • High-purity, high-density ceramics minimize loss
  • Wide range of resonant frequency
  • Low temperature coefficient

Applications

  • Mobile phone circuit systems such as 900MHz, 1.8GHz, 2.4GHz, 5.8GHz
  • Filter and duplexer, Land mobile radio, Burglar alarms, Tank circuits
  • Multi-channel microwave communications systems
  • Wireless headphone, wireless security system
  • CDMA/PCS/WLL/IMT2000
  • Oscillators (DRO/VCO)
