The LMH2121 is an accurate fast responding power detector/RF envelope detector. Its response betweenan RF input signal and DC output signal is linear. The typical response time of 165 ns making it suitablefor an accurate power setting in handsets during a rise-time of RF transmission slots. It can be used in allpopular communication standards 2G/3G/4G/WAP.
