PMI Model ERDLVA-218-CW-LPD-100 is a CW Immune, Extended Range Detector Logarithmic Video Amplifier (ERDLVA) designed for ultra low DC power consumption. This model operates over the 2.0 to 18.0GHz frequency range and offers a log slope of 77mV/dB into a 100 Ohm video load. This model provides very high speed, excellent flatness and accuracy in an ultra small hermetically sealed housing measuring only 2.04" x 1.67" x 0.472".
