AC ELECTRICAL CHARACTERISTICS (continued)
(MAX2165 EV kit, VCC = +2.75V to +3.3V, VRF_AGC = VBB_AGC = 2.3V (maximum gain), VOUT = 1VP-P, 75Ω system impedance, reg-
isters set according to the specified default register conditions, TA = -40°C to +85°C, unless otherwise noted. Typical values are at
VCC = +2.85V, TA = +25°C, unless otherwise noted.) (Note 1)
