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)
