Foreword

GB/T 27700 "quality assessment of surface acoustic wave (SAW) filter" is divided into the following sections. --- Part 1. Generic specification; --- Part 2. Guide; --- Part 3. Dimensions. This part of GB/T 27700 Part 2. This section drafted in accordance with GB/T 1.1-2009 given rules. The partial modification using IEC 60862-2.2002 "assessed quality of surface acoustic wave (SAW) filters - Part 2. Guide" (In English). This part of IEC 60862-2.2002 made some technical changes related to the technical differences have been incorporated into the text and a single vertical line identification They relate in terms of margin. We give a list of these technical differences and their causes in Appendix A for reference. In addition, this section also removed IEC 60862-2.2002 standard introduction. This section proposed by the People's Republic of China Ministry of Information Industry. This part of the National Focal frequency control and selection piezoelectric devices Standard Committee (SAC/TC182). This section drafted by.

1 Scope

SAW filters are widely used in this Part of the TV, satellite communications, fiber optic communications and mobile communications. Since these SAW filters with different performance. So it may be divided into a few basic categories. This section includes a variety of surface acoustic wave filter structure, the operating frequency range of the SAW filter structure is about 10MHz ~ 3GHz range, relative bandwidth of the center frequency of 0.02% to 100%. Purpose of the enactment of this section is not a theoretical explanation, at the same time, this section does not solve the practical problems that may occur. This section aims Users will be set forth in the order of a new use of surface acoustic wave filter before some of the basic issues that should be considered, so that users get the performance Compliant products. This part of the standard as well as detailed specifications given by the manufacturer released defines the nominal frequency, passband bandwidth of the passband, shape factor And a terminal impedance index. This section lists a large variety of surface acoustic wave filter having a typical performance. But it should not be too strong Users tune in any case should be the selection criteria for surface acoustic wave filters, in order that he may use standard SAW filters Cause only small changes in the circuit. This is particularly for surface acoustic wave filter nominal frequency selection.
