SDLVA-18G40G-65-CD-292FF-A15 Active

Successive Detection Log Video Amplifier (SDLVA)

Quantic PMI Model SDLVA-18G40G-65-CD-292FF-A15 is a successive detection log video amplifier (SDLVA) that operates between the 18 to 40 GHz frequency range. It has a dynamic range of 67 dB, a log slope of 25 mV/dB and a nominal video bandwidth of 32 MHz. This design uses cutting edge GaAs technology which provides excellent performance and reliability in a compact package making it an optimum solution for high-speed channelized receiver applications.
