AC ELECTRICAL CHARACTERISTICS
(MAX2117 Evaluation Kit: VCC = +3.13V to +3.47V, VGC1 = +0.5V (max gain), TA = 0°C to +70°C. Default register settings except
BBG[3:0] = 1011. Typical values measured at VCC = +3.3V, TA = +25°C, unless otherwise noted.) (Note 1)

VGC1 is set to 0.5V (maximum RF gain) and BBG[3:0] is
adjusted to give a 1VP-P baseband output level for a

Starting with the same BBG[3:0] setting as above, VGC1
is adjusted to back off RF gain by 10dB (Note 7)
