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.
