Maxim Integrated 

SiGe, High-Linearity, 2300MHz to 4000MHz

Upconversion/Downconversion Mixer with LO Buffer

5.0V SUPPLY AC ELECTRICAL CHARACTERISTICS (DOWNCONVERTER MODE,

fRF = 3100MHz to 3900MHz, LOW-SIDE LO INJECTION) (continued)

(Typical Application Circuit with tuning elements outlined in Table 1, VCC = 4.75V to 5.25V, RF and LO ports are driven from 50I

sources, PLO = -3dBm to +3dBm, PRF = 0dBm, fRF = 3100MHz to 3900MHz, fLO = 2800MHz to 3600MHz, fIF = 300MHz, fRF > fLO,

TC = -40NC to +85NC. Typical values are at VCC = 5.0V, PRF = 0dBm, PLO = 0dBm, fRF = 3500MHz, fLO = 3200MHz, fIF = 300MHz,

TC = +25NC. All parameters are guaranteed by design, unless otherwise noted.) (Note 6)
