(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under
conditions of internal self-heating where TJ > TA.
(2) All limits are specified by design or statistical analysis
(3) Turn-on time is measured by connecting a 10 kΩ resistor to the RFIN/EN pin. Be aware that in the actual application on the front page,
the RC-time constant of resistor R2 and capacitor C adds an additional delay.
(4) Typical values represent the most likely parametric norm.
(5) Power in dBV = dBm + 13 when the impedance is 50Ω.
