    2.4.4.2 ESD Protection ESD protection is a discretionary requirement and only required, if necessary, for higher ESD specifications than those provided by the RYZ014A. It is recommended to select an ESD device with very low capacitance and small size (0201) to avoid impacting the RF impedance.

  • Page 16: Ant_Lte Specific Footprint Design

    • Avoid routing of noisy signal tracks adjacent to RF transmission lines to minimize cross-coupling into RYZ014A’s RF ports. • The component pads of the SMD parts used in the 3-component π/T-type matching circuit are effectively very short transmission lines. To minimise the RF insertion loss (s11, VSWR) caused by the width step, use tapered ends.
