SDLVA-0R71R3-75-CD-3Model SDLVA-0R71R3-75-CD-3 is a successive detection log video amplifier that operates over the 700 to 1300 MHz frequency range. This model has a Dynamic Range of 75 dB, a log slope of 40 mV/dB.  The log linearity is ±1.2 dB typical from -65 to +5 dBm input power levels and a typical TSS of -70 dBm. The limited IF Output is +5 dBm  typical.  This model offers very fast rise times of 9 nsec and fall times of 25 nsec typically. 

The housing measures 3.75” x 1.50” x 0.50” and is gold plated.
