17-27GHz Down-Converter
CHR3664-QEG
Typical Board Measurements
Tamb = +25°C, VD = VDL = 4.0V, VGL = -0.6V, VGM = -0.7V, P_LO = 0dBm
If no specific mention, the following values are representative of onboard measurements (on
connector access planes) as defined on the drawing at paragraph “Evaluation mother board”.
The board losses are estimated from 1.5 to 2dB in the frequency range.
Conversion Gain in Supradyne Mode versus RF Frequency & GCx
F_RF = 2xF_LO+F_IF, F_IF = 2.0GHz
Board losses de-embedded (result given on package access planes)
