Note A: Based on junction temperature T J = T C + ( θ JC x V CC x I CC ). This formula can be used when the temperature of the
exposed paddle is known while the device is soldered down to a PCB. See the Applications Information section for details.
The junction temperature must not exceed +150°C.
Note B: Junction temperature T J = T A + ( θ JA x V CC x I CC ). This formula can be used when the ambient temperature of the EV kit
PCB is known. The junction temperature must not exceed +150°C. See the Applications Information section for details.
Note C: T C is the temperature on the exposed paddle of the package. T A is the ambient temperature of the device and PCB.
*Maximum reliable continuous input power applied to the RF, LO, and IF ports of this device is +15dBm from a 50 Ω source.
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.
DC ELECTRICAL CHARACTERISTICS
(Typical Application Circuit, V CC = +4.75V to +5.25V, no RF signals applied, T C = -40°C to +85°C. IF+ and IF- are DC grounded through
an IF balun. Typical values are at V CC = +5V, T C = +25°C, unless otherwise noted.)
