(VCC = +2.7V to +5.5V, RBIAS = 1.2kΩ, no RF signal applied, RFIN and RFOUT are AC-coupled and terminated to 50Ω, TA = -40°C to
+85°C. Typical values are at VCC = +3.0V, TA = +25 °C, unless otherwise noted.) (Note 1)
(MAX2644 EV kit, VCC = +3.0V, fRFIN = 2450MHz, PRFIN = -30dBm, input and output are terminated to 50Ω, RBIAS = 1.2kΩ,
TA = +25°C, unless otherwise noted.) (Note 2)
Note 1: Devices are production tested at TA = +25°C. Minimum and maximum values are guaranteed by design and characteriza-
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 (f1 = 2445MHz, f2 = 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).
