RFFC0085 Typical Performance Curves Absolute Maximum Ratings Parameter Rating Unit Supply Voltage (VDD) -0.3 to +3.6 V Operating Temperature (TOP) -40 to +85 °C Storage Temperature (TSTG) -65 to +150 °C Junction Temperature (TJ)9 9 ° C RF Input (VAGC=0V DC) for an IF OUT=1V P-P 30 dBmV RF Input (VAGC=3V DC) for an IF OUT=1V P-P -24 dBmV Operation of this device beyond any one of these limits may cause permanent dam- age. For reliable continuous operation, the device voltage and current must not exceed the maximum operating values specified in the table on page one. Caution! ESD sensitive device. Exceeding any one or a combination of the Absolute Maximum Rating conditions may cause permanent damage to the device. Extended application of Absolute Maximum Rating conditions to the device may reduce device reliability. Specified typical perfor- mance or functional operation of the device under Absolute Maximum Rating condi- tions is not implied.
