Sub-band enhancement
The performances of this product can be enhanced in sub-bands using external matching
components such as very simple combination of micro-strip stubs.
For some sub-bands, matching networks have been implemented and some typical results
are shown below. For further details see the application notes listed below.
Matched Sub-band
17-20GHz

Of course, based on the Sij matrix given previously, more accurate, or dedicated frequency
boards may be derived.
The following graphs show S parameters obtained thanks to the external matching networks
described in the application notes quoted in the list above.
