5.0 DC and AC Electrical Characteristics
Unless otherwise specified, all limits are guaranteed to V
(Note 4)
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model: 1.5 kΩ in series with 100 pF. Machine model, 0Ω in series with 100 pF.
Note 3: The maximum power dissipation is a function of T
(T
Note 4: 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 T
Note 5: Power in dBV = dBm + 13 when the impedance is 50Ω.
Note 6: All limits are guaranteed by design or statistical analysis
Note 7: Typical values represent the most likely parametric norm.
Note 8: Device is set in active mode with a 10 kΩ resistor from V
pin using a 100 pF coupling capacitor.
Note 9: Turn-on time is measured by connecting a 10 kΩ resistor to the RF
of resistor R
