RF power calculations - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hello Everyone, can anyone point me in the right direcction on how I can calculate the maximum power a filter network can manage with certain SMT components? thank you.

Most circuit simulators allow you to measure power dissipation in each component - even reactive components when you have s-parameter files or enter a Q value. Once you have the output measurements set up, crank up input power until the max power dissipation is reached in any component.

For capacitors, also monitor the voltage drop across it to not excede the working voltage and for inductors, do not excede the max current. No one said it would be easy. :-D

Keep in mind that the power dissipation will be denendent on the VSWR at each port.
