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 Filters
RF & IF Filters 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.

Saw Resonators (TSR)
SAW Resonators
Surface
Acoustic Wave
SAW Resonators (TSR) Can
Replace LC Elements and Quartz Crystals
Preview
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.

Definition of SAW
Surface Acoustic Wave (SAW) is a wave propagating along the surface of an elastic substrate.
sFrequency of SAW is:
F=V/λ
Where V is the velocity of SAW (~3,100m/s), λ is the IDT period.
What is a SAW Filter
A surface acoustic wave (SAW) is a type of
Substrate Interdigital
mechanical wave motion which travels
Transducer
along the surface of a solid material. The
(IDT)
wave was discovered in 1885 by Lord
Rayleigh, and is often named after him.
Rayleigh showed that SAWs could explain one
component of the seismic signal due to an earthquake,
a phenomenon not previously understood. These days,
these acoustic waves are often used in electronic
Package
devices. At first sight it seems odd to use an acoustic
Basic SAW Device
wave for an electronic application, but acoustic waves
have some particular properties that make them very attractive for specialized purposes. And they are
not unfamiliar-many wristwatches have a quartz crystal used for accurate frequency generation, and this
is an acoustic resonator though it uses bulk acoustic waves rather than surface waves.
A basic SAW device (Figure-1) consists of two interdigital transducers (IDTs) on a piezoelectric
substrate such as quartz. The IDTs consist of interleaved metal electrodes which are used to launch
and receive the waves, so that an electrical signal is converted to an acoustic wave and then back to an
electrical signal. A basic advantage is that acoustic waves travel very slowly (typically 3000 m/s), so
that large delays are obtainable. The IDT geometry is capable of almost endless variation, leading to
a wide variety of devices. Starting around 1970, SAW devices were developed for pulse compression
radar, oscillators, and bandpass filters for domestic TV and professional radio. In the 1980s the rise of
mobile radio, particularly for cellular telephones, caused a dramatic increase in demand for filters. New
high-performance SAW filters emerged and vast numbers are now produced, around 3 billion annually.

(Figure-2) shows a SAW travelling along the plane surface of a solid material. As the wave passes, each
atom of the material traces out an elliptical path, repeating the path for each cycle of the wave motion.

Piezoelectricity for SAW
For electronic devices, we need to generate the SAWs from an electrical input signal, and then use the SAW
to generate an electrical output signal. The conversion process (electric to acoustic, or acoustic to electric) is
called ‘transduction.’ To explain this, we first have to consider piezoelectricity, which is a property of many
solid materials. In a piezoelectric material there is a mechanism which offers coupling between electrical
and mechanical disturbances. Hence, application of an electric field sets up mechanical stresses and strains.
Conversely, a mechanical stress due to pressure, for example, gives an electric field, and hence a voltage.
Quartz Orientations

Figure-3 - Quartz Orientations
Piezoelectricity occurs in many materials but there is a
primary requirement that the material must be anisotropic,
so that its properties depend on the orientation relative to
the internal arrangement of the atoms. Usually, this means
that crystalline materials must be used. The commonest
materials for SAWs are crystals of quartz, lithium niobate
or lithium tantalate, which are all piezoelectric. In these
crystals the SAW motion is similar to that of the isotropic
case described earlier, though with the difference that the
wave now has an electric field associated with it. Another
important factor is because the material is anisotropic, the
SAW properties depend on the orientation at which the
substrate has been cut from the original material, so this
must be specified. Examples of cuts are shown in (Figure-3).

What is SAW filters
SAW designers normally use ‘standard’ orientations known to give good SAW properties. An example is 34° Y-X
quartz, meaning that the SAW propagates in the crystal X-direction, on a plate with the surface normal rotated
34° from the Y-axis. Rotated Y cuts of quartz in this region give parabolic frequency temperature characteristics,
and hence provide excellent temperature stability. The turnover temperature may be varied by adjusting the cut
angle. Many of these rotated Y cuts are given special names such as ST for 42.75°, CT for 38°, AT for 35.25°. As
for isotropic materials, the waves are nondispersive (velocity independent of frequency), and the attenuation can
be very low.
Piezoelectricity is a great help for transduction. If an electric field is applied to the surface, corresponding
stresses are set up which travel away from the source in the form of SAWs. The easiest method is to use a set of
interleaved electrodes alternately connected to two bus bars, as in (Figure-1). The left transducer is launching
the waves. When a voltage is applied, the gaps between electrodes have electric fields and, via the piezoelectric
effect, mechanical stresses.
The fields and stresses alternate in sign because of the alternating connections of the electrodes,and the stresses
act as sources of surface waves. If the frequency is chosen such that the SAW wavelength equals the transducer
pitch, the waves generated by subsequent gaps are all in phase and therefore reinforce each other. For a given
voltage, a longer transducer will give a larger wave amplitude. The transducer on the right is the same structure
but used to receive the waves, i.e. to give an output voltage in response to an incident wave. It operates in a
reciprocal manner to the launching transducer, so a longer transducer will give a larger voltage for a given SAW
amplitude.

SAW Filters Fundamentals
SAW devices consist of two transducers with interdigital transducers of thin metal electrodes deposited
on a piezoelectric substrate such as quartz or lithium tantalite. One of these acts as the device input
and converts signal voltage variations into mechanical surface acoustic waves. The other IDT is used
as an output receiver to convert mechanical SAW vibrations back into output voltages. Such energy
conversions require the Interdigital transducers to be used in conjunction with elastic surfaces that are
also piezoelectric ones.
