RF IN
Mixer RF Input port. For a 50
Ω match at 900MHz use a 15nH series
inductor. This pin is NOT internally DC-blocked. An external blocking capac-
itor must be provided if the pin is connected to a device with DC present. A
DC path to ground (i.e. an inductor or resistor to ground) is, however,
acceptable at this pin. If a blocking capacitor is required, a value of 22pF is
recommended.To minimize the mixer’s noise figure, it is recommended to
have a RF bandpass filter before this input. This will prevent the noise at
the image frequency from being converted to the IF.
