The LMH6517EVAL evaluation board is designed to aid in the characterization of TI`s High Speed LMH6517 Digital Controlled Variable Gain Amplifier. Use the evaluation board as a guide for high frequency layout and as a tool to aid in device testing and characterization.
The LMH6517 DVGA has differential input and differential output. To aid evaluation with 50 ohm, single ended test equipment the LMH6517EVAL-R1 evaluation board is shipped with transformers on both the input and output signal paths. The single ended signal path uses the IN+ and OUT+ marked connectors. The IN- and OUT- signal paths are grounded and the SMA connectors are not installed.
