IEC 63155:2020

Guidelines for the measurement method of power durability for surface acoustic wave (SAW) and bulk acoustic wave (BAW) devices in radio frequency (RF) applications

IEC 63155:2020 defines the measurement method for the determination of the durability of radio frequency (RF) surface acoustic wave (SAW) and bulk acoustic wave (BAW) devices, such as filters and duplexers, with respect to high power RF signals, which are used in telecommunications, measuring equipment, radar systems and consumer products. RF BAW devices include two types: those based on the film bulk acoustic resonator (FBAR) technology and those based on the solidly mounted resonator (SMR) technology.
This document includes basic properties of failure of RF SAW/BAW devices, and guidelines to set up the measurement system and to establish the procedure to estimate the time to failure (TF). Since TF is mainly governed by the RF power applied in the devices, discussions are focused on the power durability.
It is not the aim of this document to explain the theory, or to attempt to cover all the eventualities which can arise in practical circumstances. This document draws attention to some of the more fundamental questions which will need to be considered by the user before he/she places an order for an RF SAW/BAW device for a new application. Such a procedure will be the user's means of preventing unsatisfactory performance related to premature device failure resulting from high-power exposure of RF SAW/BAW devices.

Lignes directrices relatives à la méthode de mesure de la durabilité de puissance des appareils à ondes acoustiques de surface (OAS) et des appareils à ondes acoustiques de volume (OAV) dans les applications de radiofréquence (RF)

L'IEC 63155:2020 définit la méthode de mesure pour la détermination de la durabilité des appareils de radiofréquence (RF) à ondes acoustiques de surface (OAS) et à ondes acoustiques de volume (OAV), tels que les filtres et les duplexeurs, pour ce qui est des signaux RF de puissance élevée qui sont utilisés dans les télécommunications, les équipements de mesure, les systèmes radars et les produits de consommation. Les appareils RF à OAV sont de deux types: le premier se fonde sur la technologie du résonateur acoustique de volume de couche (FBAR, film bulk acoustic resonator), le second se fonde sur la technologie du résonateur monté solidement (SMR, solidly mounted resonator).
Le présent document inclut les propriétés de défaillance de base des appareils RF à OAS et à OAV et des lignes directrices afin de configurer le système de mesure et d'établir la procédure pour estimer la durée de fonctionnement avant défaillance (TF). La TF étant principalement régie par la puissance de radiofréquence appliquée dans les appareils, les études se concentrent sur la durabilité de puissance.
Le présent document n'est pas destiné à expliquer la partie théorique ni à traiter toutes les éventualités qui peuvent se produire dans la pratique. Il attire l'attention sur certaines des questions fondamentales que l'utilisateur a besoin de prendre en considération avant de commander un appareil de radiofréquence à OAS ou à OAV pour une nouvelle application. Cette procédure protège l'utilisateur contre des performances non satisfaisantes de l'appareil relatives à une défaillance prématurée causée par l'exposition de celui-ci à une puissance élevée.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 63155 has been prepared by IEC technical committee 49:
Piezoelectric, dielectric and electrostatic devices and associated materials for frequency
