CHR2295_15 Datasheet, PDF (4/6 Pages) United Monolithic Semiconductors – 24-30GHz Integrated Down Converter

CHR2295
24-30GHz MFC Down Converter
Typical On-board Measurements
Bias Conditions : Vdm= Vdl= 3.5V, Vgm= Vgx= -0.9V, Vgb= Vga= -0.3V
All these measurements include the losses from the test board (typically 1dB for the
conversion gain and 0.5dB for the Noise Figure).
