+5.0V SUPPLY, HIGH-SIDE LO INJECTION AC ELECTRICAL CHARACTERISTICS

(continued)

(Typical Application Circuit optimized for the standard RF band (see Table 1), VCC = 4.75V to 5.25V, RF and LO ports are driven

from 50Ω sources, PLO = -3dBm to +3dBm, PRF = -5dBm, fRF = 2300MHz to 2900MHz, fLO = 2650MHz to 3250MHz, fIF = 350MHz,

fRF < fLO, TC = -40°C to +85°C. Typical values are at VCC = 5.0V, PRF = -5dBm, PLO = 0dBm, fRF = 2600MHz, fLO = 2950MHz,

fIF = 350MHz, TC = +25°C, unless otherwise noted.) (Note 7)
