LMH6629: LMH6629

Part Number: LMH6629

Hello,

Could you please describe how to measure the plot of Noise Figure (dB) VS  Rs. For example, the Figure 58 of LMH6629.  

Thank you very much

Best regards

Kailyn

    Hi Kailyn,

    "Figure 58 is a plot of NF vs RS with the circuit of Figure 52 (Rf = 240 Ω, AV = +10V/V). The NF curves for both Unterminated (RT = open) and Terminated systems (RT = RS) are shown." - From the datasheet

    Figure 52 is the design configuration for that test and the datasheet explains the values for resistors. There is also another currently open E2E thread with a very similar question to yours.
    It maybe possible that a TINA simulation was done to get the noise figure plot but I am not sure. I will confirm on this to have the following E2E post as well as your question answered.

    Thanks!
