Low LO Leakage Base-Station Rx/Tx Mixer

AC ELECTRICAL CHARACTERISTICS (Downconverter Operation) (continued)

(MAX2043 Typical Application Circuit, VCC = +4.75V to +5.25V, RF and LO ports are driven from 50Ω sources, PLO = -3dBm to

+3dBm, PRF = 0dBm, fRF = 1700MHz to 3000MHz, fLO = 1900MHz to 3000MHz, fIF = 200MHz, fRF < fLO, TC = -40°C to +85°C,

unless otherwise noted. Typical values are at VCC = +5V, PRF = 0dBm, PLO = 0dBm, fRF = 1900MHz, fLO = 2100MHz, fIF = 200MHz,

TC = +25°C, unless otherwise noted.) (Note 1)
