Model: SDLVA-250M6G-CD-1   


PMI model SDLVA-250M6G-CD-1 Successive Detection Log Video Amplifiers (SDLVA) offers 70dB Dynamic Range over the frequency range of 0.25 to 6.0 GHz.  This model offers an ultra-fast rise time of 10 nsec maximum and a recovery time of less than 60 nsec.  The unit is temperature compensated such that log linearity over temperature remains less than +/-2.5 dB over the full operating temperature range of -40 to +70C.  This model is supplied in a compact housing measuring only 3.2" x 1.8" x 0.4".  [Optional frequency ranges covering 100MHz to 26.5GHz are available.]
