Introduction

GB/T 43186 "Quality-rated Surface Acoustic Wave (SAW) and Bulk Acoustic Wave (BAW) Duplexers" aims to provide surface acoustic wave (SAW) the general requirements, quality assessment procedures, appearance and terminal drawings of bulk acoustic wave (BAW) duplexers are planned to be composed of three parts.

---Part 1: General specifications. The purpose is to specify the terms and definitions of surface acoustic wave (SAW) and bulk acoustic wave (BAW) duplexers, divided into categories and characteristics, and quality assessment procedures.

---Part 2: User Guide. The purpose is to provide the basic structure and operation of surface acoustic wave (SAW) and bulk acoustic wave (BAW) duplexers.

The operating principle is used to provide guidance for users to reasonably select resonators and meet their usage needs.

---Part 3: Standard shape and terminal connection. The purpose is to provide surface acoustic wave (SAW) and bulk acoustic wave (BAW) duplexers Commonly used outline drawings and terminal function definitions.

Quality-rated surface acoustic waves (SAW) and Bulk Acoustic Wave (BAW) Duplexer Part 2: User Guide

1 Scope

This document applies to duplexers. The function of the duplexer is to separate the receiving signal and the transmitting signal, and is a key component in two-way wireless communication.

Duplexers are usually used in CDMA mobile communication systems, such as narrowband code division multiple access (N-CD-MA), Wideband Code Division Multiple Access (W-CDMA)/Universal Mobile Telecommunications System (UMTS) in the third generation mobile communication system (3G) or fourth generation Long-term evolution (LTE) of mobile communication systems (4G).

This document looks at some basic questions about the principles of surface acoustic wave and bulk acoustic wave duplexers and how to use them, that is, what the user needs to do Issues to consider before purchasing surface acoustic wave and bulk acoustic wave duplexers for new applications. This document is to ensure that users get satisfactory performance.

Since surface acoustic wave and bulk acoustic wave duplexers have very similar performance characteristics, it would be convenient for users to use one standard for these two types of duplexers.
