Transmission line question.

  1. Feb 12, 2007 #1
    If I have a section of transmission line, with a characteristic impedance Z0, how does the standing wave ratio in that section change as a function of the frequency of operation?

    Doesn't the stading wave ratio just depend on the characteristic impedance of the line, and the load impedance?

    Yes, the VSWR ratio depends only on the magnitude of the reflection coefficient, which is a function of the load impedance and characteristic impedance. However, in general, the load impedance will be a function of frequency, so the VSWR will be as well.

    Finding the Input Impedance at z = 0 (the load) is equal to the load impedance, maybe? If so, don't the tan(Bl) all cancel anyway since l = 0?

    Which would make sense wouldn't it?
