17-24GHz Integrated Down Converter

United Monolithic Semiconductors 

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.
