Token SAW Resonator employs surface acoustic wave, and is able to be applied to high frequency circuit
where conventional crystal, ceramic resonators are not available, as SAW Resonator oscillates stably with its
fundamental mode over frequency range from 200 MHz to around 1 GHz.
The SAW
resonator uses arrays of metal strips, with pitch λ/2, as reflectors of the waves. These arrays can give
strong SAW reflections, and two arrays can be used to form a SAW cavity with high Q. Such resonators are often
used for high-stability oscillators.
TSR can be applied to many types of high frequency devices
including RF remote controls, CATV FSK demodulators and
CATV 2nd local oscillators. TSR resonator is ideal for applications
such as automotive keyless entry, tire pressure monitoring, gate
and door openers, personal and home security, automated meter
readers, wireless point of sale terminals, identification tags, bar
code readers, and computer peripherals.
Token offers 2 types SAW Resonator in terms of 1-port type and 2-port type.
1-Port Type:
- One-port, typically one-pole, SAW Resonators are used in oscillator applications.
- Most of the application circuit is Colpitts or similar type that can be made with low cost.
- 1-port resonator is basically a 2 terminal device and its application is similar to that of quartz
bulk wave resonator or ceramic resonator.
- Also, it is also applicable to VCO (Voltage Controlled Oscillator) application.
2-Port Type:
- 2-port SAW
Resonator is a kind of very narrow, low loss band-pass filter.
- Oscillation circuit is mostly like a RF amplifier with feedback loop.
- There are many varieties of two-port (multi-pole) resonator structures in production.
The TSR Resonator series has high stability, good temperature characteristics provided by quartz crystal substrate
and is developed with SAW technology accumulated for SAW filters through Token’s experience. In addition,
TSR Resonator can be customed designs and other frequency requirements available on request.
