1 Introduction

The THS6222RHFEVM is an evaluation module for the single THS6222 amplifier in the RHF package. This evaluation module is designed to quickly and easily demonstrate the functionality and versatility of the amplifier. The EVM is ready to connect to power, signal sources, and test instruments through the use of onboard connectors. The EVM comes configured for easy connection with common 50-Ω laboratory equipment on its inputs and outputs. The amplifier is configured for a differential input with a gain of 10 V/V to a differential output. The board includes jumpers to easily switch the device between different bias modes and a potentiometer to set the value of the IADJ pin. The EVM can be easily configured for other gains and for single- or split-supply operation. The output transformer and resistors are configured to present a 50-Ω, single-ended output.
