5.8 GHz One Antenna Reflective Tag

CHR2244-QDG

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.
