Exceeding any one or a combination of the Absolute Maximum Rating conditions may Supply Voltage -0.5 to +6.0 V DC cause permanent damage to the device. Extended application of Absolute Maximum Rating conditions to the device may reduce device reliability. Specified typical Input RF Level at F<2.3GHz +5 (see note) dBm performance or functional operation of the device under Absolute Maximum Rating conditions is not implied.

RFMD reserves the right to change component circuitry, recommended application circuitry and specifications at any time without prior notice. NOTE: Exceeding any one or a combination of the above maximum rating limits may cause permanent damage. Input RF transients to +15dBm will not harm the device. For sustained operation at inputs >+5dBm, a small dropping resistor is recommended in series with the V in order to limit the current due CC to self-biasing to <32mA. Furthermore, while the LNA is in Bypass Mode, and for sustained operation at the input, +10dBm is the maximum recommended power level for Frequencies above 2300MHz. +5dBm is the maximum recommended power level for Frequencies <2300MHz.
