What is BS EN 61019-2 - Surface acoustic wave (SAW) resonators about?
BS EN 61019-2 is the second part of a multi-series standard used for surface acoustic wave (SAW) resonators that specifies the fundamentals and characteristics of these SAW resonators. BS EN 61019-2 can be your best practice guide in using surface acoustic wave (SAW) resonators.
BS EN 61019-2 define the available combinations of resonance frequency, quality factor, motional resistance, parallel capacitance, etc. BS EN 61019-2 are compiled to include a wide range of SAW resonators with standardized performances. BS EN 61019-2 cannot be over-emphasized that the user should, wherever possible, select his SAW resonators from these specifications, when available, even if it may lead to making small modifications to his circuit to enable the use of standard resonators. BS EN 61019-2 applies particularly to the selection of the nominal frequency.
Note: SAW resonators are now widely used in a variety of applications: VCR RF-converters, CATV local oscillators, measuring equipment, remote control, and so on. While SAW resonators are also applied to narrow bandwidth filters, the scope of this part of IEC 61019 is limited to SAW resonators for oscillator applications
Note: It is not the aim of this guide to explain a theory, nor to attempt to cover all the eventualities which may arise in practical circumstances. This guide draws attention to some of the more fundamental questions, which should be considered by the user before he places an order for a SAW resonator for a new application. Such a procedure will be the user's insurance against unsatisfactory performance.

Why should you use BS EN 61019-2 - Surface acoustic wave (SAW) resonators?
Surface acoustic wave (SAW) resonators are the surface-wave equivalent of the crystal resonator. These resonators are used extensively for stabling the frequency sources and filters. Surface acoustic waves can be used for flow measurement.
BS EN 61019-2 specifies the fundamentals of these Surface acoustic wave (SAW) resonators. This helps in achieving the resonance phenomenon for SAW resonators by confining the SAW vibration energy within grating reflectors. With the help of BS EN 61019-2, you can determine the characteristics of these SAW resonators.
BS EN 61019-2 provides best practice guidelines regarding the usage of these SAW resonators. This can also guide you in applying these oscillator circuits in these resonators. This helps in standardizing the manufacturing process of these SAW resonators.
