DANSK DSF/PREN IEC 63155 PDF

This International Standard 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. The IEC 63155 includes basic properties of failure of RF SAW/BAW devices, and guidelines to setup the measurement system and to establish the procedure to estimate their time to failure (TF) of RF SAW/BAW devices. Since TF is mainly governed by the applied RF power in the devices, discussions are focused on the power durability. It is not the aim of this standard to explain theory, nor to attempt to cover all the eventualities which may arise in practical circumstances. This standard draws attention to some of the more fundamental questions, which shall 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 insurance against unsatisfactory performance related to premature device failure resulting from high-power exposure of RF SAW/BAW devices.
