Hi,
I have to agree with Brian.
I also find it hard where to begin.
Like this comment or not: it is no HF design. I can see any design at all.
A PCB layout is not simply joining some pins of electronic parts.
"Joining" in the meaning of electrical connection, but even this is not true for all pins of your PCB. (Connector, diode)
You think you now have a HF suitable GND plane. But it is not. In many cases your "GND plane" is not better than traces.
You need to take care about current flow, current loops (mind that a singal is not from A to B you always need to consider the return path very carefully. If the return path is bad, your signal is bad and thus the performance of the whole circuit is bad.
Sadly a forum can't replace school, reading books, experience...
You can't expect to learn a HF design within a forum thread in a couple of hours where other need years of school.
I design industrial electronics for decades now, always touching HF design, but after all the years I'm far away to be an HF expert.
I just know some basics.
But I don't want to discourage you. Go on. Maybe with another - not that high frequency - circuit.
Maybe with this circuit ... but read some books about HF design first..
