Transmitter / Amplifier matching
You are so far out of your depth it isn't even funny, rf power amplifier are NOT good beginner fodder.

Seriously, cut and splice 'design' does not usually end well when it is a UHF amplifier you are working on, you can pull it off if you copy entire 50 ohm blocks, (50R in, 50R out, with everything between those points copied), but lifting bits of matching never works out.

Why does all the stuff in red on the left of the '5324 even exist? 
You have a DC bias injection circuit there that makes no sense, a T network that does some matching to an unspecified impedance, this is then followed by a second matching network in black (C1, C3 and the matching line Lambda 1), seems overly complex to me. 

On the output side you have a matching network (Lambda 2, C2, R2, C7 followed by an output LPF (But you don't know the LPF input side design impedance).   

Also, I see no details of the transmission lines used for matching the amplifier.

The data sheet gives a set of S parameters that are a good starting point for this sort of thing (But only a starting point, the scattering parameters are small signal). Do a bit of reading, grab a Smith chart and you can probably have a reasonable first cut of something workable in an hour or so.
