SAW Filters (TSF) Make New Waves
in The Wireless World
Preview
With the growth of wireless communications, SAW 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 designs.
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
applications.
A new compact range of RF SAW filters uses chip-scale
packaging specifically to address the demanding miniaturisation
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
devices.
Our experienced engineering team can support your SAW application from the initial design through
production. Custom designs are available utilizing high technology mask designs, wafer fabrication,
assembly and complete reliability testing.
For marketing discontinuations or second sourcing activities concerning RF Filter and IF Filter
products, you are encouraged to contact our Sales Department so the request can be properly directed
within Token.
