CC2511: Meaning of 'Ref Lev' in radiation pattern

Part Number: CC2511

https://www.ti.com/lit/an/swra117d/swra117d.pdf 

In 5.2 radiation pattern, 'Ref Lev' is mentioned but there is no explanation about it.

I assume it will be 'reference level' and want to know exact meaning.

Thank you in advance

  • Hi,

    The "Ref Lev" is the reference level at the perimeter of the lobe plots. 

    Each division of the scale of the lobe plots are specified as well. i.e. 4 dB / division so this can be used together with the reference level to read the exact level at any angle.

    Regards,
