RF FILTERS & RESONATORS

One of the main products of Token China Power Precision Components Inc.

Dielectric Filters, Resonators, Coaxial, Patch Antenna

As a world manufacturer in the development of ceramic piezo technology, Tokenchina had been able to develop specialized piezo materials which when combined with an advance design have resulted in a complete line of practical, inexpensive ceramic piezo dielectric devices for entertainment and communications applications.


Tokenchina manufactures Dielectric Microwave Components -
Band Pass Filters, Resonators, Coaxial, and Patch Antenna are widely used in:
Wireless Cellular Phones and Cable Televisions, Cellular Base Stations Direct Broadcast Satellite Receivers, Automobile Collision Avoidance Sensors, and so on. Token dielectric microwave components are material with high Q, good temperature stability, and high d constant enables design of stable microwave oscillators. It utilizes the latest piezo technology enabling the most cost-effective designs to be housed in the lowest profile packages for extremely high performance within limited space. SMD and reflow soldering is available and mountable by automatic placing machine.


Custom dielectric packages are also available. Please consult our sales representatives or engineers as regards the products of other frequency.

Ceramic Resonators (Murata compatible)

Tokenchina resonators utilize the mechanical resonance of piezoelectric ceramics which provide various vibration behaviors depending on the resonance frequency. Conventionally, quartz crystal resonators are also well known mechanical resonators.


Tokenchina resonator provides the following features:

  • Stable oscillation frequency - In terms of oscillation accuracy, the ceramic-resonator is ranked between quartz resonators and LC/CR oscillation circuits.
  • Compact and lightweight - are approximately half the size of general quartz resonators.
  • Low-cost and adjustment-free oscillation circuit - have been designed for use in mass production. In principle, the resonators are hardly affected by fluctuations in external circuit or power supply voltage, providing highly stable oscillation without the necessity of adjustment.

Please contact our piezo engineering group for IC characterization at the beginning of your design process. Tokenchina offers two extending frequency range in MHz and KHz.
