AC ELECTRICAL CHARACTERISTICS (continued)
(MAX3580 EV kit, VCC = +3.1V to +3.5V, VGND = 0V. VRF_AGC = VBB_AGC = +2.85V, RF input terminated into a 75 load, BBI_ and
BBQ_ loaded by RL greater than 2k and CL less than 10pF, VCO active, registers are set according to the recommended default
register conditions, unless otherwise noted. Typical values are at VCC = +3.3V, TA = +25°C, unless otherwise noted.) (Note 1)

Note 1:
Part is tested at room temperature only. Performance at cold and hot temperature is guaranteed by design and characteri-
zation.
Note 2:
The specified overall voltage gain is suitable to amplify -93dBm to -20dBm to 1VP-P at the baseband output.
Note 3:
Guaranteed by design characterization over the specified operating conditions. Not production tested.
Note 4:
BB_AGC adjusted for gain = 72dB with RF_AGC at 2.85V.
Note 5:
Two tones at a) 230MHz and 431MHz with IM measured at 201MHz and b) 230MHz and 701MHz with IM measured at
471MHz.
Note 6:
Two tones at 499MHz and 689MHz with IM measured at 879MHz.
Note 7:
IM3 measured with two tones within the adjacent channel at a) 205.75MHz and 210.5MHz with IM measured at 201MHz
and b) 475.25MHz and 479.5MHz with IM measured at 471MHz.
Note 8:
Measured at RF = 171MHz with harmonics at 511MHz (3rd harmonic) and 851MHz (5th harmonic).
Note 9:
Delay of 2ns equal 2.74° phase error.
Note 10: UHF rolloff of 4dB in addition to gain flatness specification.
Note 11: Production tested at VCC = +3.5V to limits of 1.7V -0.12/+0.1V.
Note 12: Operation in the VHF band requires the R-divider = 2.
Note 13: Operation of the N-divider at values below 12 is not tested or guaranteed.
