    Part Number: LMH6629 Other Parts Discussed in Thread: CC2592 , CC2590 Dear Team, Our customer is looking for 2.4G low noise amplifier which can supports 11ax or 11be. Do we have any suitable solution can meet the spec? Thanks a lot. Many Thanks, Jimm…

  • LMH6629: LMH6629: Input Referred Current Noise past 10 MHz

    Part Number: LMH6629 The datasheet of the LMH6629 lists the input referred current noise spectral density as 2.6 pA/rHz at 1 MHz and also plots the input referred current noise in figure 32. However, this plot only goes out to 10 MHz. I am interested…

  • LMH6629: Output impedance for in the loop compensation

    Resolved
    Part Number: LMH6629 Hi TI forums, How can I find the output impedance of the LMH6629? I am having issues with it being unstable (set to a closed loop gain of 40). I'd like to try in the loop compensation, which needs an estimate of the output resistance…

  • RE: LMH6629: High-Speed Transimpedance Amplifier for Single-Photon Detection

    Resolved
    Hi Charles, Charles Gervasi said: what is the reason for connecting the decoupling caps to ground with a via and connecting the feedback path without a via. I didn't say that feedback components must not be put on the bottom plane being connected by vias…

  • LMH6629: noise optimization

    TI Thinks Resolved
    Part Number: LMH6629 Hello, On page 26 the datasheet advises: "If bias current cancellation is not a requirement, then Rf || Rg does not need to equal Rseq. In this case, according to Equation 3, Rf || Rg should be as low as possible to minimize noise…
