  • LMH6521: Output impedance match

    Resolved
    Part Number: LMH6521 Tool/software: Hi Team, The out put circuit in the Typical Application show as below, but it said that the output impedance of LMH6521 is 20Ohm. It seem that the Zal=40.2+100+40.2=180Ohm, will it cause mismatch? How to understand…
