H Confidential and Proprietary – Qualcomm Technologies, Inc. 9 MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION 1 Introduction 1.1 Documentation overview This device specification defines two RF transceivers: the WTR4605 and the WTR4905 devices. Throughout this document, the devices are referred to as the WTR4x05 device when material being presented applies to both of them. The WTR variants are distinguished by the airlink technologies they support:  WTR4605 – 3GPP2 CDMA 1X to DOrA, 3GPP WCDMA Rel 99 to DC-HSPA+, 3GPP GSM to EDGE, and TD-SCDMA  WTR4905 – All airlinks supported by WTR4605, plus 3GPP LTE FDD and TDD Technical information for the WTR4x05 wafer-level transceiver is primarily covered by the documents listed in Table1-1. All documents should be studied for a thorough understanding of the device and its applications. Released WTR4x05 device documents are available from the CDMATech Support website at https://support.cdmatech.com. Table1-1 Primary WTR4x05 device documentation Document Title/description number 80-NL713-1 WTR4905/WTR4605 Wafer-level Transceiver Device Specification (this document) Provides all WTR4x05 device electrical specifications and mechanical information. Additional material includes pin assignments; shipping, storage, and handling instructions; printed circuit boards (PCB) mounting guidelines; and part reliability. This document can be used by company purchasing departments to facilitate procurement. 80-NL713-4 WTR4905/WTR4605 Wafer-level Transceiver Device Revision Guide Provides a history of WTR4x05 device revisions, explains how to identify the various device revisions, and discusses known issues (or bugs) for each revision and how to work around them. 80-NL713-5 WTR4905/WTR4605 RF Transceiver Design Guidelines/Training Slides  Detailed functional and interface descriptions for the WTR4x05 device  Key design guidelines are illustrated and explained, including:  Technology overview  DC power distribution  Interface schematic details  PCB layout guidelines  External component recommendations  Ground and shielding recommendations 80-NL713-1 Rev.
