The log video slope is 25 ±1.5 mV/dB as defined by the best fit straight line of the video output voltage, measured over the typical input signal range of -67 to +3 dBm. The channel-to-channel isolation between pairs is specified at 50 dB minimum. The unit requires a power supply of 5V or 6V, with total consumption of about 2W. It's housed in a dual flat pack with a surface area of about 1.3 in. sq. Mounting is accomplished via four through-hole threaded flanges and overall thickness is less than 0.22".
