Model: DLVA-2G4G-45-70-CD-1      


PMI Model No. DLVA-2G4G-45-70-CD-1is a detector log video amplifier (DLVA) that operates between the 2.0 to 4.0GHz frequency range.  It has a dynamic range of 45dB, a log slop of 70mV/dB and a nominal video bandwidth of 14MHz.  Furthermore, the DLVA has features that can convert any incoming signal ranging from 50ns to CW to a pulsed output of 600ns.  In addition, the DLVA will not trigger an output with input pulse widths of 40ns or less.  This state of the art design utilizes cutting edge technology which provides stunning performance and reliability in a compact package making it an optimum solution for high speed channelized receiver applications.
