Operating Case Temperature……………………-40°C to +105°C

Supply Voltage (VDD33 to GND) .........................-0.3V to +3.8V

Supply Voltage (VDD18 to GND) .........................-0.2V to +2.2V

Input Voltage (1.8V pins)........................-0.2V to VDD18 + 0.2V

Input Voltage (3.3V pins)........................-0.3V to VDD33 + 0.3V

Input into the BALUN (RMS)............................................+7dBm

Operation at +25°C, AVDD18 = 1.8V, AVDD33 = 3.3V, DVDD18 = 1.8V, and 20MHz external clock, unless otherwise specified.

Note 1: Peak current includes supply decoupling network. Refer to Hardware Design Guide for proper sizing of the on-board

regulators.

Note 2: Characterized at typical voltages, +25°C operating case temperature, and 20MHz input signal BW.

Note 3: Continuous adaptation, tracking (100% duty-cycled feedback).

Note 4: Power dissipation may be FW dependent. Refer to the FW release notes for any changes to values listed above.

Note 5: Duty-cycled feedback power dissipation averaged over ON time of 100ms (9%), OFF time of 1.0s (91%).

Note 6: See Operating Frequency Ranges table for frequency limits of each defined band.

power delta between the two outermost carriers must be ≤ 20dB, the carrier configuration must be static (no hopping), the

Note 8: Correction performance across range of input signal BWs also depends on PA output power and carrier configuration.

Note 9: Worst case over supply voltage and temperature range, guaranteed by characterization.

Note 10: Spurious content is typically due to RFPAL receiver LO leakage and is located within 1MHz of the occupied signal center

frequency.
