Dave,
Thanks for the hint.
1- Would you recommend to clean all 3 elements of the matching network, as I don't know which component will go where ?
2- If you look at the trace between the components, you'll see I made the trace the same width as the pad. Is this a good idea ? The pad's center to center is 4mm. The trace 0.9 wide, with a surrounding ground plane and via fencing I treat it as a coplanar wave guide and the rest of the trace and clearance are in accordance with that. The idea behind making the trace between the component is to avoid width bumps.
3- Is my via fencing overkill putting them shoulder to shoulder ? Would a 1/10th of 1/4 wave spacing be enough for a coplanar wave guide ?
4- Could you suggest me a type of inductor in particular that would appropriate in the 0603 package for what I'm doing ?
BTW, Yesterday I took a reading with the board flat outside its case. I had installed 2 ferrite in a row along the cable. I had a VSWR of 1.19:1 all across the bandwidth from 900 to 930MHz which is better than the spec sheet. If only I could get below 2 while in its case...
Thanks,
