6 / 10 page ![]() 6 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. DC CHARACTERISTICS PARAMETER MIN TYP MAX UNITS Supply Voltage (VDD33 to GND) 3.1 3.3 3.5 V Supply Voltage (VDD18 to GND) 1.7 1.8 1.9 V Supply Peak Current (VDD33 to GND) 1,2,3, 5 59 mA Supply Peak Current (VDD18 to GND) 1,2,3, 5 592 mA Average Power Dissipation: Full-Scale Adaptation, Track, and PMU 3, 5 1060 mW Average Power Dissipation: Duty-Cycled Feedback 2,4,5 420 mW 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. RADIO FREQUENCY SIGNALS PARAMETER SYMBOL CONDITIONS MIN RECOMMENDED MAX UNITS Operating Frequency 1 f 698 2800 MHz RFIN_BLN Range for Maximum Correction PRFIN_BLN_P Peak power -4 4 6 dBm RFIN_BLN Range for Maximum Correction PRFIN_BLN RMS power 2 -9 -6 -4 dBm RFFB_BLN Range for Maximum Correction PRFFB_BLN_P Peak power -14 -4 -2 dBm RFFB_BLN Range for Maximum Correction PRFFB_BLN RMS power 2 -19 -14 -12 dBm RFIN_BLN Operating Range PRFIN_BLN RMS power 2 -40 -4 dBm RFFB_BLN Operating Range PRFFB_BLN RMS power 2 -45 -12 dBm RF Input Signal Peak-to Avg. Ratio 3 PARIN CCDF 4 probability=10 -4 5 to 10 dB Input Signal Bandwidth BWsignal 1.2 40 or 60 5 MHz Noise Power 6 Referred to 0dBm at PA input -138 -135 dBm/Hz 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. |
