CC1310: SWRC319 / LaunchXL-CC130 Schematic | Inductor L22 Different Values Across Reference Designs

Hi,

I have several of the reference design schematics and am laying out the RF portion of the system.  (I'm sure I"ll have some trace width / impedance questions later).

I noticed a variation from the LAUNCHXL-CC1310 (Rev 1.3.0) vs. TIDA-01519, REV E1. 

On LAUNCHXL-CC1310 (Rev 1.3.0), I am talking about inductor L22 (which is 27nH).

I see this inductor value on TIDA-01519, REV E1, as 18nH.

Is this dependent on some PCB stackup factor?

Should we just use the 27nH value?

Thanks,
