Demodulating the logarithmic amplifier, convert an input signal to a corresponding decibal scale output voltage precisely Wide bandwidth from 1 MHz to 8 GHz, ± 1.0 dB over a 55 dB range with high precision Adopts the technique of compression on a cascade amplifier chain so that each stage has a detector cell Can be configured to supply drive voltage to a VGA, convenient for users Small dimension LFCSP, built-in temperature sensor, bipolar SiGe high speed process, professional and convenient Material:plastic colour:black Package Contents: 2 x Logarithmic Detector Mondule Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
