Analyzing a matching network

[jmsigler]

Hello, first off I am pretty new to RF/Ham stuff, so this question is pretty basic. I'm trying to figure out if there are any easy/cheep ways to accurately measure the impedance of a matching network attached to an IC? I have made a cc1101 based comms circuit board and would like to see how well the theory design performs in a practical application. As a related question, what is the standard way to measure radiated rf power. I.E. if I know that I am supposed to be radiating 27dBm, what would the best way to measure this be?

If you have a scope and sig gen -

Network analyzers commonly used as well.


Power measurement google "power measurement rf transmitter". Many low
cost power meters also available, bird power meter. Also circuits you can
build.
