LVD-218-70/75 (Option NI)

LVD-218-70 (Option NI) Series DLVA’s Have Extended Dynamic
Range Over
the Full 2-18 GHz Bandwidth, With True DC
Coupling and with Internal Built-In
CW/Noise Immune Circuitry.  Units Employ Planar Diode
Detectors and Integrated
Video Circuitry for High Speed Performance and Outstanding
Reliability.  The DLVAs
are of Superior Construction Using State-of-the-Art MIC/MMIC
The Size is 3.0″ X 3.5″ X 0.5″.
