| Output Section - Graphs |
|
|
|
||
| The graphical output from the Coupling Matrix Synthesis program is arranged as a number of tabbed panes, each displaying a certain combination of filter characteristics. | ||
| There are tabs for displaying the following parameters: |
||
|
||
![]() |
S21 in dB versus
group delay.
|
|
| The 'hump' around the center frequency in the group delay characteristic, is the result of a pair of complex transmission zeroes. | ||
![]() |
Loaded
Q and stored energy (10-9J/Watt) for each resonator in the
filter.
|
|
| This parameter is required in order to find out if the filter has problems with power handling and to pinpoint the resonators where breakdown may occour first. | ||
| More information on power handling analysis of Rf filters can be found in [6] & [7]. | ||
| The graphs can be arranged by changing the values on the axes. | ||
| Curve values can be red out by inserting markers. | ||
