Typical Operating Characteristics (continued)
(MAX2700/MAX2701 EV kit (Figure 3), VCC = +3.0V, TA = +25°C, SHDN = GAIN_SET = VCC, X2_EN = GND, CEXT+ connected to
CEXT-, PLO = -13dBm, FLO = 980MHz (MAX2700) and 1200MHz (MAX2701), PLNAIN = -30dBm, PRFIN = -25dBm, LNAIN and RFIN
(single-ended input to balun) driven from 50Ω source, LNAOUT terminated into load; MIX_I, MIX_Q AC-coupled to 2kΩ load; IIN1+,
QIN1+, IIN2+, QIN2+ driven from 1.1kΩ AC-coupled source; IOUT1, QOUT1 AC-coupled to 2kΩ; IOUT2, QOUT2 AC-coupled to
100Ω; input to VGAs, 20mVp-p at 1MHz tone, set VAGC = 1.25V, unless otherwise noted.)
