(Typical Application Circuit (see Table 1). R1 = R4 = 681I, R2 = R5 = 1.82kI, VCC = 4.75V to 5.25V, RF and LO ports are driven from

50I sources, PLO = -6dBm to +3dBm, PRF = -5dBm, fRF = 1200MHz to 1700MHz, fLO = 1060MHz to 1560MHz, fIF = 140MHz, fRF > fLO,

TC = -40NC to +85NC. Typical values are at VCC = +5.0V, PRF = -5dBm, PLO = 0dBm, fRF = 1450MHz, fLO = 1310MHz, fIF = 140MHz,

TC = +25NC. All parameters are guaranteed by design and characterization, unless otherwise noted.) (Note 7)
