Microwave Broadband Log Video Amplifiers

Our log log amplifiers (SDLVA and DLVA) are used to measure widely varying signals at high frequencies in applications where rapid and precise tracking is required across the entire frequency band. Signals with high density pulses, narrow pulse widths and large amplitude variations are compressed into an output video voltage response that increases linearly with increasing input power. Logarithmic video amplifier applications include: radar and EW systems used for direction finding and power monitoring, but they can also find use in laboratory measurement and test equipment as well as telecommunications and data communications systems.

These new SDLVA and DLVA logarithmic video amplifiers utilize highly efficient GaAs semiconductor technology which is beneficial for high speed applications while maintaining flatness and accuracy throughout the desired frequency band. Our 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. These new successive detection log video amplifier and detector log video amplifier product lines are highly reliable and designed to meet MIL-STD-202F environmental conditions.
