INSERTION LOSS
The graph below offers a convenient means of determining the insertion loss of filters, duplexers,
multicouplers and related products. The graph on the back page will allow you to quickly determine VSWR. I
t
should be remembered that the field accuracy of wattmeter readings is subject to considerable variance du
e
to RF connector VSWR and basic wattmeter accuracy, particularly at low end scale readings. However,
allowing for these variances, these graphs should prove to be a useful reference.
