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.

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. - SONET - Synchronous Optical Network - DECT - Digital European Cordless Telephone - GSM - Global System for Mobile Communications - VCO - Voltage Controlled Oscillator - PCS - Personal Communication System - IF - Intermediate Frequency Filter - RF - Radio Frequency Filter - 3G - Third Generation Systems - PCN - Personal Communications Network - PHS - Personal Handyphone System - CDMA - Code Division Multiple Access - SCDMA - Synchronous Code Division Multiple Access - VOFDM - Vector Orthogonal Frequency Division Multiplexing - TDMA - Time Division Multiple Access - EGSM - Extended Global System for Mobile - AMPS - Advanced Mobile Phone System - GSM - Global System for Mobile Communications - SDH - Synchronous Digital Hierarchy - DCS - Digital Communications System - PDC - Personal Digital Cellular Type of SAW devices - IEF - Impedance Element Filter - Precision - Bidirectional, High Loss - TCRF - Transversely-Coupled Resonator filter - LCRF - Longitudinally-Coupled Resonator Filter - SFIT - Slanted Finger Interdigital Transducer - SPUDT - Single Phase Unidirectional Transducer Back to 1st Page - Saw Filters (TSF) 14 of 35 http://www.token.com.tw/ rfq token.com.tw Version 2010 TOKEN 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.

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. Version 2010 http://www.token.com.tw/ rfq token.com.tw 31 of 35 TOKEN What is SAW filters (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. The atoms move by smaller amounts as one looks farther Particle Motion Propagation into the depth, away from the Direction surface. Thus, the wave is Vacuum Amplitude guided along the surface. In the simplest case (an isotropic Substrate material), the atoms move in the so-called sagittal plane, i.e. Depth the plane which includes the Basic Surface Acoustic Wave surface normal and the propagation direction. 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 Z 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). 32 of 35 http://www.token.com.tw/ Y X rfq token.com.tw Version 2010 TOKEN 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 filter is an integrated, passive device with bandpass filter characteristics. 2. Operation is based on the interference of mechanical surface waves. 3. Input/Output transducers are formed on a piezoelectric material. SAW Filters Advantages 1. Reduced size and weight. 2. High reliability and ruggedness. 3. No tuning or readjustment. 4. Mass production capable. 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. SAW Filters Manufacturing Process 1.
