RF characteristics

5. In low-power dissipation state, TA can be extended to this range as long as TJ does not exceed TJ max (see Section 6.6).

6. Junction temperature above 105 °C must be limited to 30% of 10 years life time.

1. Evaluated by characterization, not tested in production, unless otherwise specified. Measured in conducted mode, based

on reference design (see AN5165), using output power specific external RF filter and impedance matching networks to

interface with a 50 Ω antenna.

2. Suitable for systems targeting compliance with worldwide radio-frequency regulations ETSI EN 300 328 and EN 300 440

Class 2 (Europe), FCC CFR47 Part 15 (US), and ARIB STD-T66 (Japan).
