VI TELEFILTER
Application Note
______________________________________________________________________________________________________
1. General
The filter is balanced driven. It is matched to 50
The matching element values given below are valid on the test PCB. If the parasitics
on the customer PCB and on this PCB are different, the matching elements have to
be optimised regarding the circuit and PCB design.
There are ground pin thru’s underneath the filter and in the other areas of the to
decrease cross talk.
The matching elements have been chosen from the E12- series (European standard
series with fixed tolerances) to get the best agreement between the PCB
measurement and the measurement in a reference test fixture.
2. Theoretical matching
The balanced driven source and load impedances of the filter are:
source impedance:
680
|| - 2.5 pF
load impedance:
680
|| - 2.5 pF
The values of the matching elements which are given below are calculated from the
source and load impedance. If the values of the matching elements are not equal to
standard values the best standard values are given in brackets.
