Mini-Circuits’ ZV47-K44RMS+ is a high-accuracy RMS power detector that covers a wide RF input band- width from 100 MHz to 40 GHz. The DC output voltage of the detector provides an accurate representation of the average signal power applied to the RF input. This device provides a linear-in-dB response with 29mV/dB logarithmic slope over its 35 dB dynamic range with typically better than ±1 dB accuracy. It comes in a compact, gold over nickel plated brass alloy case (0.84 x 0.96 x 0.37″) with 2.92mm RF connectors.
