someone was having a better result with the 1 watt board:
I have removed all shunt caps and things got a wee bit better. I then added 1p at the device in and out and now have about 9 dB gain at 2.4 GHz at 400mW.
I may leave it this way for the moment but i think i will be taking a knife to the wider part of the lines on the input and output.
So keep on trying!! Cor
