Monitor the power level

Hi all,

I want to monitor the power at the output of each stage of my high power amplifier. Can any help me with this please?
Thank you

Re: Monitor the power level

Hi,

without more info of your amp design ....

here are 2 suggestions....

1) if the stages follow each other on the same PCB layout then have a stripline directional coupler between the stages from which you will able to derive a RF voltage.

2) if the amplifier stages are separate (ie modular) then a you can use a Narda
or some other brand directional coupler between the stages with your choice of connector say N type or SMA

cheers
