CHR3663-QEG_15 Datasheet, PDF (5/18 Pages) United Monolithic Semiconductors – 17-24GHz Integrated Down Converter
17–24GHz Down Converter
CHR3663-QEG
Typical Measured Performances
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.
