hi all;

I want to design a simple power meter that works on frequency range from few KHz to few MHz. Can anyone help me?
thanks alot
 

Re: power meter

Thank you very much for your help but is this circuit capable of measuring power over the required frquency range and is it capable of measuring the power for the CDMA system.
 

Re: power meter

Hi, Analog devices has special IC's for this and also National. look for RF true power detector at Analog site and power detector at the national site. they work from 50 MHz up-to a few Ghz and can measure CDMA and other digital waveforms.

Paul.
