TELEFILTER
1. General
The filter is driven single ended. 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.
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:
480
|| -9.8 pF
Load impedance:
1030
| -5,95 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.
