IEC 63155 defines the measurement method for the determination of the durability ofradio 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 intelecommunications, measuring equipment, radar systems and consumer products. RF BAWdevices include two types: those based on the film bulk acoustic resonator (FBAR) technologyand those based on the solidly mounted resonator (SMR) technology.This document includes basic properties of failure of RF SAW/BAW devices, and guidelines toset 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 arefocused on the power durability.It is not the aim of this document to explain the theory, or to attempt to cover all theeventualities which can arise in practical circumstances. This document draws attention tosome of the more fundamental questions which will need to be considered by the user beforehe/she places an order for an RF SAW/BAW device for a new application. Such a procedurewill be the user's means of preventing unsatisfactory performance related to premature devicefailure resulting from high-power exposure of RF SAW/BAW devices.
