The TRF1305EVM is designed to provide a quick setup to evaluate the TRF1305 series of fixed gain fully differential amplifiers (FDA) that have high linearity and 3dB bandwidth of the order of 6.5GHz. The TRF1305 are available in both single-channel and dual-channel packaging with three different fixed gains in each packaging. These amplifiers work with two flexible supply rails and can be dc-coupled and support a wide range of common-mode voltage. There are four types of EVMs that cover all device variants in the configurations.

• Configured for split-supply operation and easily modified for single supply
• Single-ended or differential input signals
• Designed for easy connection to standard 50Ω input and output impedance test equipment
• Power down option available onboard using a jumper connector

This document is the user's guide for the evaluation boards (EVMs) meant for testing dual channel TRF1305 series of amplifiers in D2D configuration. There are four types of TRF1305 EVMs that are meant to test all device variants in different I/O configuration as shown in Table 1-1 below.

This document also includes schematic diagrams, a bill of materials (BOM), printed-circuit board (PCB) layouts, and test block diagrams. Throughout this document, the abbreviations EVM, EVM or the term evaluation module means any one of the four EVMs listed above. This user's guide describes the basic steps and functions that are required for the proper operation and quick setup of the -EVM. Many sections in this user's guide are common to all TRF1305EVMs.

Table 1-2 lists the contents of the EVM kit. Contact the Texas Instruments Product Information Center nearest you if any components are missing. TI highly recommends that users check the TI website to verify that the latest versions of the related software is being used.
