CHR3694-QDG_11 Datasheet, PDF (5/18 Pages) United Monolithic Semiconductors – 37-40GHz Integrated Down converter

37-40GHz Down Converter
CHR3694-QDG
Typical Measured Performances
Tamb = +25°C, VDX=VDL = 4V, Typical VGX = -0.9V & VGM= -0.7V, P_LO=1dBm
These values are representative of onboard measurements (on connector access planes)
as defined on the drawing 97445 page 16 for CHR3694-QDG and drawing 97342 page 17
for CHR3794-QDG. The board loss is estimated to 2 to 3dB in the frequency range.
