Downmixer Applications: (Test Circuits Shown in Figures 1 and 2)
Note 3: Specifi cations over the –40°C to 85°C temperature range are
assured by design, characterization and correlation with statistical process
control.
Note 4: SSB Noise Figure measurements performed with a small-signal
noise source and bandpass fi lter on RF input and no other RF signal
applied.
