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 1: Devices are production tested at T
A
= +25°C. Minimum and maximum values are guaranteed by design and characterization
over temperature and supply voltages.
Note 2: Min/Max limits are guaranteed by design and characterization.
Note 3: The part has been characterized at the specified frequency range. Operation outside this range is possible but not guaranteed.
Note 4: Excluding PC board losses (0.3dB at the input and 0.3dB at the output of the MAX2644 EV kit).
Note 5: Measured with two input tones (f
1
= 2445MHz, f
2
= 2455MHz) both at -30dBm per tone. Input IP3 can be improved to
+1dBm with circuit shown in Figure 2.
Note 6: Excluding PC board losses (0.3dB typical at the input of the MAX2644 EV kit).
