CHR3762-QDG Datasheet, PDF (5/16 Pages) United Monolithic Semiconductors – 5.5-9GHz Integrated Down Converter

5.5-9GHz Integrated Down Converter
CHR3762-QDG
Typical Board Measurements
Tamb.= +25°C, VD1= VD2= VD3= +3V, VG1= -0.45V, VG2= -0.35V, VG3= -0.45V,
VG4= -1V, P_LO = +5dBm
These values are representative of onboard measurements as defined on the drawing in
paragraph "Evaluation mother board". Data are given in the package access planes.
