LVD-218-50 Options 818, CW, LC, MD

LVD-218-50 Options 818, CW, LC, MD DLVA’s Are Special DLVA’s
For Low Current
Consumption, 8 to 18 GHz and for CW Applications.  Other
DLVA’s Are Available in
Standard 50 dB and Extended 70/75 dB Dynamic Range Over the
Full 2-18 GHz Bandwidth,
With True DC Coupling.  Units Employ Planar Diode
Detectors and Integrated Video Circuitry
For High Speed Performance and Outstanding Reliability. 
The DLVA’s are of Superior
Construction Using State-of-the-Art MIC/MMIC Technology.
