1.
The listed values are contained on the evaluation board to achieve optimal broadband performance
2.
For lower cost and performance (500 – 4000 MHz) option use 18 nH air core wire wound inductor.
3.
Place holders for the 0
Ω resistors and “Do Not Place” references are not needed for final design.
