Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
CAUTION! ESD SENSITIVE DEVICE
DC ELECTRICAL CHARACTERISTICS
(VCC = +2.7V to +4.8V, no RF signals applied, LNAGAIN = unconnected, VVCOON = 2.4V, VRXON = VMOD = VDIV1 = 0.45V, PREGND
= GND, TA = TMIN to TMAX. Typical values are at TA = +25°C, VCC = +3.3V, unless otherwise noted.) (Note 1)

Note 1: ≥25°C guaranteed by production test, <25°C guaranteed through correlation to worst-case temperature testing.
Note 2: Calculated by measuring the combined oscillator and prescaler supply current and subtracting the oscillator supply current.
Note 3: Calculated by measuring the combined oscillator and LO buffer supply current and subtracting the oscillator supply current.
Note 4: Calculated by measuring the combined receive and oscillator supply current and subtracting the oscillator supply current.
With LNAGAIN = GND, the supply current drops by 4.5mA.
