EMI filtering is very good regarding suppression of interference caused by high power TX signals or interference to RX frequency bands caused by data signal harmonics in mobile phones. All pins are protected against ESD of ±15 kV according to IEC61000-4-2 (contact discharge). The wafer level package is a green package with a size of only 2.1 mm x 1.7 mm and a total height of 0.6 mm.
