6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
SUPPLY VOLTAGE
 VDD - GND 3.6 V
RF INPUT
 Input power 10 dBm
 DC voltage 400 mV
Enable input voltage VSS – 0.4 V < VEN < VDD + 0.4 V
Junction temperature(2) 150 °C
Maximum lead temperature (soldering, 10 seconds) 260 °C
Storage temperature, Tstg –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The maximum power dissipation is a function of TJ(MAX) , RθJA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA)/RθJA. All numbers apply for packages soldered directly into a PC board.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±2000
Machine model ±200
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) 2.7-V DC and AC Electrical Characteristics 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 ensured by test or statistical analysis.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and also depend on the application and configuration. The typical values are not tested and are not specified on shipped production material.
(4) All limits are ensured by design and measurements which are performed on a limited number of samples. Limits represent the mean ±3–sigma values. The typical value represents the statistical mean value.
(5) This parameter is ensured by design and/or characterization and is not tested in production.
