SRF of matching components in your reference design

[victor]

Hi, we looked at your BOM for matching components in your file: www.nordicsemi.com/.../15787782 for QFAC variant of the IC. You use LQP15MN27NG02D as 27nH inductor which has an SRF of 2.5GHz, the inductance at 2.4GHz is somewhere from 100nH to infinity, should we use this inductor or should a 27nH inductor at 2.4GHz be used as specified in "nRF51822 Product Specification v3.1" under 11.5.1.1

The purpose of the inductor (L2) is to lead DC to the PA (VDD_PA), so the inductance at 2.4 GHz is not important.
