The HMC610LP4(E) is a true RMS power detector capable of providing a 1 dB measurement dynamic range of more than 70 dB. It converts any RF input signal at its differential input, regardless of modulation or waveform complexity, to an accurately scaled linearin-dB output response that is equivalent to the RootMean-Square (RMS) of the input waveform. For normal operation, the RMSOUT pin is shorted to the VSET input, and will provide a nominal logarithmic slope of 37 mV/dB and an intercept of -70 dBm for frequencies up to 2 GHz; other slopes are achieved with external resistors connected between RMSOUT and VSET pins. Temperature stability is excellent with 0.5 dB error from -40C to 85C maintained from 100 MHz to 3.9 GHz.
