WebIt may also be calculated by dividing termination impedance by characteristic impedance, or vice versa, which ever yields the greatest quotient. A line with no standing waves (perfectly matched: Z load to Z 0) has an SWR equal to 1. Transmission lines may be damaged by the high maximum amplitudes of standing waves. http://www.anuraghyd.ac.in/ece/wp-content/uploads/sites/8/MWE-Lab-Manual.pdf

WebNotice that the VSWR dips quite low at the very same points where the coupler provided exactly 3 dB coupling and 90 degree phase. Not a coincidence! But at band center, the worst case match is 8.5 dB. What happens is the termination on port 4 is not matched? We reanalyzed the network with 25 ohm termination.
