VI TELEFILTER
1. General
The filter is designed single ended use at the input and at the output.
The terminating impedances are
input:
740
|| -7.9pF single ended
output:
880
|| -6.2pF single ended
The matching element values given below are calculated from the terminating impedances.
If the values of the matching elements are not equal to standard values the best standard
values are given in brackets. Because these are theoretical values they have to be modified
on PCB’s corresponding to the existing parasitics.
2. Theoretical matching to 50
The theoretical values of the stated elements are:
L1 = 150 nH
L3 = 165 nH (180 nH)
L2 = 164 nH (150 nH)
L4 = 250 nH (220 nH)
