CHR2244
5.8 GHz One Antenna Reflective Tag
Evaluation board
Important notice / design recommendations:
Device slug should be connected to RF ground plane through multiples vias (>=9).
An external matching may be required to optimize RF performances on 50Ω impedance, versus substrate
height.
A RF ground plane height of 0.008” (0.203mm) under the component (evaluation board) provides the
highest RF performances thanks to low RF ground inductance and low pin to pin coupling.
Substrate = FR4
Metallic layers qty = 3
Thickness = 0.6mm + 0.2mm
