ABSOLUTE MAXIMUM RATINGS
Supply Voltage (VDD33 to GND) ...... -0.3V to +3.8V
Supply Voltage (VDD18 to GND) ..... -0.2 V 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
Junction Temperature .................................. +150°C
Storage Temperature .....................-65°C to +150°C
OPERATING RATING
Operating Case Temperature……-40°C to +100°C
Warning: Any stress beyond the ranges indicated may damage
the device permanently. The specified stress ratings do not imply
functional performance in these ranges. Exposure of the device
to the absolute maximum ratings for extended periods of time is
likely to degrade the reliability of this product.

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) and Power Measurement Unit active or inactive.
Note 4: Duty-cycled feedback power dissipations averaged over ON time of 100ms (9%) and OFF time of 1.024s (91%).
Note 5: Power dissipation may be FW dependent. Refer to the FW release notes for any changes to values listed above.

Note 1: See Operating Frequency Ranges table for frequency limits of each defined band.
Note 2: A peak to average ratio (PAR) of 5dB to 10dB is used for this table.
Note 3: Higher PAR values can be supported but at a reduction to a combination of the input signal range and IM correction limits.
Note 4: CCDF = Complementary cumulative distribution function; a measurement of peak to average ratio or crest factor.
Note 5: > 40MHz operation requires a fully occupied signal bandwidth.
Note 6: Worst case over PVT guaranteed by bench characterization.
