PART NUMBER DERIVATION:
LC11 *(T) **(R) -50M -50 -65A
1 2 3 4 5 6 7
1) Series, LC
2) Number of poles, 11
3) The “T” option specifies a filter with low THD for
ADC/DAC testing. When selected the minimum
THD is > -80dBc, -96dBc typical.
4) “R” RoHS compliant. Allow for longer lead time.
5) f-3dBc
6) Terminations
7) Case selection from the case selection guide.
“T” option cases are larger than standard.

STOPBAND FREQUENCY CALCULATIONS:
Using part number LC11-50M-50-65A, we know
that the filter is an 11 pole Chebyshev lowpass
filter. Scroll down to series number LC11. Moving to
the right we find the stopband specification listed as
-60dBc minimum at 1.4 x f -3dBc. Thus, the -60dBc
frequency is at 70 MHz (1.4 x 50 MHz
