Dual RMS Detector IC Measures Signal Power
Wed, 01/14/2009 - 9:43am
Hittite Microwave Corporation introduces its integrated dual RMS power detector that is capable of simultaneously measuring the instantaneous power (RF envelope) and the average true RMS power of any input RF signal from 0.1 to 3.9 GHz. The HMC714LP5E is a dual-channel RMS power detector for high accuracy RF power signal measurement and control applications in the 0.1- to 3.9-GHz frequency range. It also provides "channel difference" output ports that permit measurement of the input signal power ratio between the two power detection channels. Suitable for dual-channel wireless infrastructure systems, the power detector can be used with input signals having rms values from -55 to 15 dBm and large crest factors with no accuracy degradation.
