FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61019-2 has been prepared by IEC technical committee 49:
Piezoelectric and dielectric devices for frequency control and selection.
This second edition cancels and replaces the first edition published in 1995. This edition
constitutes a technical revision.
The main changes with respect to the previous editon are listed below:
• at the end of 5.1, the edge reflector has been added. Its reference literature has been
inserted in the bibliography;
• in Table 1, the propagation properties of LiNbO (64° Y) have been added;
• in Table 3, the clause and subclause numbers have been corrected in order to be
consistent with IEC 61019-1 (2004) which has replaced IEC 61019-1-1 (1990) and IEC
61019-1-2 (1993).

INTRODUCTION
This part of IEC 61019 gives practical guidance to the use of SAW resonators which are used
in telecommunications, radio equipments and consumer products. IEC 61019-1 can be referred
to for general information, standard values and test conditions.
The features of these SAW resonators are small size, light weight, adjustment-free and high
stability. In addition, the operating frequency of SAW resonators extends to the VHF and UHF
ranges.
This part has been compiled in response to a generally expressed desire on the part of both
users and manufacturers for a guide to the use of SAW resonators, so that the resonators
may be used to their best advantage. To this end, general and fundamental characteristics
have been explained in this guide.

SURFACE ACOUSTIC WAVE (SAW) RESONATORS –

Part 2: Guide to the use
1 Scope
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
It is not the aim of this guide to explain 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.
Standard specifications, such as those of the IEC of which this guide forms a part, and
national specifications or detail specifications issued by manufacturers, will define the
available combinations of resonance frequency, quality factor, motional resistance, parallel
capacitance, etc. These spe
