70 DB True RMS Power Detector SMT, 0.1 - 3.9 GHz
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 compexit, to an accurately scaled linear-in-dB output response that is equivalent to the Root-Mean-Square (RMS) of the input waveform.
The 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 staibility is excellent with 0.5 dB error from -40C to 85C maintained from 100 MHz to 3.9 GHz.
Low frequency operation determined by external components.
