This model operates on a single +5 VDC supply and consumes less than 130 mA of current. This model is highly temperature compensated such that the log linearity is better than +/-1 dB over the temperature range of -54 to +85 °C.
This model has a logging range of -40 dBm to 0 dBm with an output log video voltage of 10 mV to 2.25 V. This model features a fast rise / fall time of 25ns/30ns and a recovery time of less than 40nsec. This unit is listed as having an operating temperature range of -54 to +85 ºC, but is designed to operate at extended temperature ranges up to +95 °C.
