Is there a component list error on the MAX2112 EVKit datasheet?

No, although the reference designators used are non-standard. The components on the MAX2112 evaluation kit are used to form a resistive match from a 50Ω signal generator source to the 75Ω input impedance of the MAX2112 RF_IN.  On the MAX2112, RF_IN is matched to 75Ω and only a DC-blocking capacitor is needed at the input for a 75Ω system.  For more details, refer to the typical application circuit on sheet 17 of the MAX2112 datasheet.  

Evaluation Kit Values:
  • L1 = 33 pF Capacitor
  • C22 = 43.2 OHM Resistor
  • R8 = 86.6 OHM Resistor
