CHR3663-QEG Datasheet, PDF (4/16 Pages) United Monolithic Semiconductors – 17-24GHz Integrated Down Converter GaAs Monolithic Microwave IC in SMD package

CHR3663-QEG
17–24 GHz Down Converter
Typical Measured Performances
Tamb = +25°C, VD = VDL = 4.5V, VGL=-0.4V, VGM = -0. 7V, P_LO = 0 dBm
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 2dB
in the frequency range.
