General Description
The HMC614LP4E RMS Power Detector is designed for RF power measurement, and control applications for frequencies up to 3.9 GHz. The detector provides a “true RMS” representation of any RF/IF input signal. The output is a temperature pensated, monotonic representation of real signal power, measured with a differential input sensing range of 71 dB. The HMC614LP4E is ideally suited to those wide bandwidth, wide dynamic range applications, requiring repeatable measurement of real signal power; especially where RF/IF wave shape and/or crest factor change with time. The HMC614LP4E provides an indication of the instantaneous or peak input power level normalized to the average input power level (peak to average power ratio) via the IPWR output. The capability of simultaneously measuring the instantaneous power (envelope power) and the average true RMS power provides crucial information about the RF input signal: Peak Power, Average Power, Peak to average power and RF Wave-Shape.
