(

Typical Application Circuit, R1 = R4 = 681Ω, R2 = R5 = 1.5kΩ, VCC = 4.75V to 5.25V, RF and LO ports are driven from 50Ω sources,

PLO = -3dBm to +3dBm, PRF = -5dBm, fRF = 1700MHz to 2000MHz, fLO = 2050MHz to 2350MHz, fIF = 350MHz, fRF < fLO, TC = -40°C

to +85°C. Typical values are at VCC = 5.0V, PRF = -5dBm, PLO = 0dBm, fRF = 1850MHz, fLO = 2200MHz, fIF = 350MHz, TC = +25°C.

All parameters are guaranteed by design and characterization, unless otherwise noted.) (Note 6)
