Abstract: A root-mean-square (RMS) detector includes detection circuitry having as an input a radio frequency signal, target voltage and a set voltage and a RMS signal as an output, and a gain stage within the detection circuitry to produce the RMS signal as an output. The gain stage provides for faster settling times of the detector.

Abstract: A system has a baseband gain stage to receive incoming in-phase and quadrature voltage signals and output in-phase and quadrature current signals, a mixer core arranged to receive the in-phase and quadrature current signals and output radio frequency signals, and a variable gain amplifier to receive the radio frequency signals and produce a broadband radio signal.
