PMI Model No. SDLVA-218-44-70M is a detector log video amplifier (DLVA) designed to operate over the 2.0 to 18.0 GHz frequency range. This model offers a logging range of -40 to +4 dBm having a log slope of 70 mV/dB. The logging linearity is better than ±0.75 dB and the rise time is 25 nsec maximum and the fall time 300 nsec maximum.
This model operates on ±15 VDC and is supplied in a small housing measuring only 2.2" x 1.5" x 0.4".
