AGC

= 1.25V, CEXT+ con-

nected to CEXT-; no RF input signals applied; RFIN, LNAIN, LO inputs are terminated with 50Ω, LNAOUT connected to V

through a

10nH inductor; MIX_I, MIX_Q, QIN1+, QIN1-, QOUT1, IIN1+, IIN1-, IOUT1, QIN2+, QIN2-, QOUT2, IIN2+, IIN2-, IOUT2 pins are

unconnected; T

= -40°C to +85°C, unless otherwise noted. Typical values are at V

= +3.0V, T

= +25°C.)

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.
