STOPBAND FREQUENCY CALCULATIONS:
Using part number SE36-80M-50-585, we know
that the filter is a 7 pole Elliptical Function
lowpass filter. Scroll down to series number
SE36. Moving to the right we find the stopband
specification listed as -60dBc minimum at 1.35 x
f -3dBc. Thus, the -60dBc frequency is at 108 MHz
(1.35 x 80 MHz).
