The HMC614LP4E provides a "true RMS" representation of any RF/IF input signal and is ideally suited to wide bandwidth, wide dynamic range applications requiring repeatable power measurement over temperature; and especially where RF/IF waveshape and crest factor change with time. The HMC614LP4E employs an innovative circuit architecture which enables simultaneous measurement of peak power and average power. A peak-to-average ratio output signal provides a direct read of signal crest factor.

The HMC614LP4E provides a differential input sensing range of 72 dB, to ±1 dB detection accuracy up to 3.9 GHz with excellent crest factor immunity and temperature stability. Operating from a +5V supply, the HMC614LP4E is specified for operation over the -40°C to +85°C temperature range, and is supplied in a compact 4x4 mm leadless QFN package.
