Product Feature

Quantic PMI Model SDLVA-8G18G-40-5-SFF is an 8-18 GHz Successive Detection Log Video Amplifier that is supplied in a ruggedized, hermetically sealed housing that measured only 1.2" x 0.85" x 0.4". 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; has a logging range of -40 to 0 dBm with an output log video voltage of 10 mV to 2.25 V; and features a fast rise / fall time of 25 ns / 30 ns and a recovery time of less than 40 ns. This unit is listed as having an operating temperature range of -54 to +85 °C, but is designed to operate at extended temperature ranges up to +95 °C.
