Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 4:
Input impedance is measured at the LNAIN pin. Note that the impedance includes the 15nH inductive degeneration con-
nected from the LNA source to ground. The equivalent input circuit is 50Ω in series with 2.2pF.
Note 5:
