nrf24le1 antenna transmission line

Dear All,

1. I'd like to know if below two lines which high-lighted in RED , Line width should be designed to provide 50 Ω impedance matching characteristics ? 

>>> Circled by the lighted blue are the lines mentioned above,  and looks it doesn't provide 50 Ω impedance matching characteristics because the line width is so narrow 

comparing with the line yellow high-lighted which connect to Antenna.

Hi,

 

The line you marked with green in the schematics(between B1 and J1), and yellow in the snip of the layout, should be 50 ohm. The differential lines (red in schematic, turquiose in layout), should be designed as long and as wide as in the reference design.

 

Best regards,

Andreas

Hi Andreas,

The answer is very clear for me now, Thank you very much as always!

Have a nice day~
