The basic steps and functions that are required to ensure the proper operation and quick setup of the TRF1208-EVM. This document also includes a schematic diagram, a bill of materials (BOM), printed-circuit board (PCB) layouts, and test block diagrams is outlined in this document. Throughout this document, the abbreviations EVM, TRF1208 EVM and the term evaluation module are synonymous with the TRF1208-EVM, unless otherwise noted.

The TRF1208 evaluation module (EVM) is used to evaluate the TRF1208 device, which is a single-ended input to differential output RF amplifier available in a 2 × 2-mm2, 12-pin WQFN package. The device is designed to drive a high-speed differential input ADC without using a passive balun. The TRF1208 has two gain variants TRF1208A with 16 dB gain and TRF1208B with 10 dB gain. Throughout this document TRF1208 can be referred to either TRF1208 or TRF1208B unless otherwise noted.
The board is set up for 50-Ω single-ended input matching. The amplifier has a low output impedance. The board has ac-coupling capacitors at input and output. The EVM is ready to connect to a +3.3-V power supply, signal source, and test instruments for the measurements.
