Hi...... I am trying to understand what is given in the reference design of RF Module based on STM32W108.

Here's the link:

http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/APPLICATION_NOTE/CD00270908.pdf

On page no 3, matched network is shown. I am confused about matched network because there is no clear explanation about designing of matched network.

Shall I design matched network if I want to use SMA jack (straight) antenna instead of PCB antenna?

Please reply as soon as possible.

RF design is a very specific skill - some say a ''black art'' - you're not going to learn it in a forum post!

Probably best to seek out a specialist designer, or buy a ready-made module...

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
