17–24GHz Down Converter
Typical Measured Performances
CHR3663-QEG
Tamb = +25°C, VD = VDL = 4.5V, VGL = -0.4V, VGM = -0.7V, P_LO = 0dBm
These values are representative of onboard measurements (on connector access planes) as
defined on the drawing 97625 page 16. The board losses are estimated from 1.5 to 2.0dB in
the frequency range.
