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.

RF & IF Filter Applications
RF & IF Filter Applications
● RF Filters (front end)
- The main key factor of insertion loss on system performance criticizes the application of resonant
design principles such as LCRF (Longitudinally-Coupled Resonator Filter), IEF (Impedance
ElementFilter), and IEF balanced bridge filters. With many year’s experience in SAW applications,
Token takes advantages of these design principles for the development of low loss filters for front
end applications.
- A combination of two port resonators can be described as an LCRF design. Typically, a parallel
connection of 4 two port resonators is used. This advantage allows very low loss by reducing resistive
losses and avoided waveguide effects.
- IEF composes the basic design principle for RF filters with one port resonators used as impedance
elements. Resonators are constituted in a ladder configuration. The difference between the acoustic
impedance of resonance and anti-resonance is used to achieved a filter performance. The resonators
may be designed to have different resonant frequencies.
- For wide-band, low-loss filters, Token takes advantage of different cuts of higher coupling substate
material (LiNbO3 / LiTaO3).- TO-220 Style Power Package, Isolated Case, Non Inductive.
● IF Filters
- There are various different design principles which are suitable for the design of IF SAW Filters.
However, to meet the requirements perfectly is working on optimization.
- Precision filter design meets most of the requirements such as phase ripple, group delay and low
amplitude in combination with high close-in rejection and fabulous selectivity. The disadvantage
of precision filters is their high insertion loss. Token SAW Resonator design makes low insertion
loss and miniaturized package size served better.
- SPUDT (Single Phase Unidirectional Transducer) filters combine transversal and resonant filter
design principles to take advantage of optimization both. By optimizing the transduction and
reflection of interdigital transducers, the filter performance can be improved while keeping the
chip size the same. As a result of internal reflections, the signal length in the time domain is increased.
- Token utilizes SFIT (Slanted Finger Interdigital Transducer) filter to provide a low insertion loss
with a wide bandwith in SAW design. Token has developed a set of practical design tools to achieve
low group delay ripple, and suppression of reflections including the triple transit signal.

SAW Grossary (TSF)
SAW Grossary
What is SAW - Surface Acoustic Wave
- SAWs were first explained in 1885 by Lord Rayleigh, who
described the surface acoustic mode of propagation and
predicted its properties in his classic paper. Named after
their discoverer, Rayleigh waves have a longitudinal and a
vertical shear component that can couple with any media in
contact with the surface.This coupling strongly affects the
amplitude and velocity of the wave, allowing SAW sensors
to directly sense mass and mechanical properties.
What is IDT - Interdigital Transducer
Type of SAW Applications
- The theory developed by Blotekjaer ET AL.,
(1973) is used to study a periodic system of
conducting electrodes deposited upon the
surface of a piezoelastic half space - a SAW
IDT. It is assumed that some of the electrodes
are fed by external voltage sources. Exact
expressions are obtained for elements of
the transadmittance matrix, coupling currents
and electrode potentials. Numerical and
experimental results are presented.
