Token Saw Filters (TSF)
Make New Waves in The Wireless World.
With the growth of wireless communications, surface acoustic
wave technology filters have become a critical component for
electronics manufacturers. Token develops and manufactures a
complete line of our frequency control products utilizing industry
standard packages in both Surface Mount and Through Hole
Token provides innovative low-cost, space-saving and
energy-efficient designs with high volume off-shore manufacturing,
leading technology and superior engineering resources in design and process manufacturing.
Token's saw filters support all the major standards: EGSM, DCS, AMPS/CDMA/GSM850, PCS,
WCDMA, WLAN, GPS, within the standard range of devices, offering a cost-effective solution for all
A new compact range of Saw RF filters uses chip-scale packaging specifically to address the
demanding miniaturization and performance requirements for new generations of mobile phones. Key
features of the range include compatibility with lead-free (high-temperature) solder reflow while
achieving high reliability against moisture, temperature, mechanical vibrations and shocks.
In modern remote control applications, Saw resonators and front end filters are key components which
transmit in the USA typically at 315 or 915 MHz and in Europe at 433.92 MHz or 868-870 MHz.
These remote controls are used in systems for Remote Keyless Entry (RKE, wireless operation of a
car's central locking system), security alarms and garage door openers, electronic toll, RFID, short
range data transmission, wireless Tire Pressure Monitoring (TPMS).
Token saw components provide stable frequencies for the RF carrier signal to transmit data over a
range for the local oscillators of superhet receivers. The front-end filter in the receiver eliminates
interference from the incoming RF signal, thus increasing selectivity and sensitivity in short-range
Our experienced engineering team can support your Saw application from the initial design through
