["Javier del Valle" <javodv@xxxxxxxx>]

Hello Warren,

I had also been looking for an RF PCB layout book but I have realized that
there is not a PCB layout focused on just RF. There are many RF books
dedicated to transmission lines (striplines, microstrip, etc.) with lots of
maths. I have found these books useful for finding where the complex
formulas come for. At the end, I bought a High Speed book (EMC and the
Printed Circuit Board Design, Theory and Layout Made Simple from Mark. I.
Montrose) but there are many others. I found that these high speed books are
good for understanding the manner in which propragation occurs, etc. from a
different perspective (not so many maths).

About the analog around your radio chip I will design the transmision line
for being a good 50Ohms line (if your dielectric filter is matched to this
impedance. You can also evaluate this filter and obtain an .S2p file with a
network analyzer and include it in the simulation). I would also place some
not mounted components for improving the matching to the filter or to the
antenna (maybe they can improve the matching). For designing the 50 Ohms
transmision line you can use programs like ADS, Apcad, or 3D electromagnetic
simulators. For the 13Mhz digital signal you should look at its spectrum and
try to design the 50Ohms line at that frecuencies.

I hope this helps, Best Regards,

Javi del Valle
