VI TELEFILTER
1. General
The filter is single ended 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 optimized regarding the circuit and PCB design.
There are ground pin thru’s under the filter and in the other area of the PCB 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 source and load impedances of the filter are:
source impedance:
1000
|| - 5.8 pF
load impedance:
1300
|| - 5.8 pF
The following theoretical matching circuit was calculated from these values:
