Instructions for exporting a design
in ADS.
If you are having trouble with an input impedance match at the front end
of your power splitter (after the LNA), you can significantly improve the
match by designing a branch-line coupler.
Here is a design that seems to
work well. You will notice that your match is relatively good at 2.4 and 2.6
GHz, but not elsewhere. You might want to check the stability of your
amplifier over a broader frequency range to ensure it remains stable.
