Minimum and maximum values are guaranteed by design and characteriza- A tion 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 = 2445MHz, f = 2455MHz) both at -30dBm per tone. Input IP3 can be improved to 1 2 +1dBm with circuit shown in Figure 2. Note 6: Excluding PC board losses (0.3dB typical at the input of the MAX2644 EV kit). Maxim Integrated 2 www.maximintegrated.com
