CHR3861-QEG_15 Datasheet, PDF (6/18 Pages) United Monolithic Semiconductors – 6-9GHz Integrated Down Converter

CHR3861-QEG
6-9GHz Down Converter
Typical Measured Performances
Tamb = +25°C, VD = VD1 = 4V, VG = -0.3V, B = -4V, 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 paragrah “Evaluation mother board”.
The board losses are estimated from 0.5 to 0.7dB in the frequency range.
Configuration 1: High linearity
