IEC EN 62575-2 Radio Frequency (RF) Collective Acoustic Wave (BAW) Filters for Quality Evaluated - Part 2: Directions for Use

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62575-2 testing. IEC EN 62575-2 provides practical guidance on the use of RF BAW filters used in telecommunications, measurement equipment, radar systems and consumer products. General information, standard values ​​and test conditions will be provided in a future IEC standard. This part of IEC EN 62575 includes various filter configurations with an operating frequency range of about 500 MHz to 10 GHz and a relative bandwidth of about 1% to 5% of center frequency.

The standard specifications given in IEC EN 62575 and the national specifications or detailed specifications published by the manufacturers include the current rated frequency, crossover bandwidth, ripple, form factor, termination impedance, etc. define combinations. These specifications have been compiled to cover a broad RF range.

It cannot be overemphasized that the user should select RF BAW filters whenever possible from these features, even though this may result in minor modifications to the circuitry to enable the use of standard filters. This applies in particular to the selection of the rated frequency.

This standard has been compiled in response to the generally expressed requests of both users and manufacturers for guidance regarding the use of RF BAW filters so that the filters can be used at their best. For this purpose, general and basic properties are explained in this part of IEC EN 62575.

It is not the purpose of this standard to explain theory or try to cover all possibilities that may arise in practical conditions. This standard draws attention to some basic questions that should be considered by the user before ordering an RF BAW filter for a new application. Such a procedure will insure the user against unsatisfactory performance.

The features of RF BAW filters are small size, light weight, no adjustment required, high stability and high reliability. RF BAW filters add new features and applications to the field of surface acoustic wave (SAW) filters and dielectric resonator filters. Today, RF BAW filters with low insertion attenuation are widely used in a variety of applications in the gigahertz range.
