STOPBAND FREQUENCY CALCULATIONS:
Using part number HE1182-100M-50-720A, we
know that the filter is an 11 pole Elliptical Function
highpass filter. Scroll down to series number
HE1182. Moving to the right we find the stopband
specification listed as -80dBc minimum at
0.83 x f -3dBc. Thus, the -80dBc frequency is at
83 MHz (0.83 x 100 MHz).
PART NUMBER DERIVATION:
HE1182 *(T) **(R) -100M -50 -720A
1 2 3 4 5 6
1) Series, HE1182 (which has 11 poles)
2) The “T” option specifies a filter with low THD for
ADC/DAC testing. When selected the minimum
THD is > -80dBc, -96dBc typical. Testing
requires a bandpass filter.
3) “R” RoHS compliant. Allow for longer lead time.
4) f-3dBc
5) Terminations
6) Case selection from the case selection guide.
“T” option cases are larger than standard.
