Pasternack announces a new line of broadband logarithmic (log) video amplifiers that cover bandwidths from 0.5 GHz to 18 GHz. The amplifiers utilize GaAs semiconductor technology, which makes them ideal for use in measuring signals at high frequencies in high speed applications.
“These log amplifiers can process up to 75 dB of dynamic range and have log linearity that ranges from ±1 to ±2.5 dBm. The log slope ranges from 20 to 50 mV/dB and they also boast fast recovery times ranging from 40 to 150 nanoseconds. The 50 ohm hybrid circuit assemblies are enclosed in rugged metal packages with SMA connectors,” according to Pasternack.
Two of the new models include a Successive Detection Log Video Amplifier (SDLVA) and a Detector Log Video Amplifier (DLVA). The SDLVA and DLVA models offer high signal sensitivity, fast recovery times, advanced temperature stability and a wide input dynamic range.
The amplifiers meet the MIL-STD-202F standard and are best suited for use in radar and electronic warfare systems. They can also be used in test equipment, telecommunications, and data communications systems.
