Maxim Integrated 

SiGe, High-Linearity, 2300MHz to 4000MHz

Upconversion/Downconversion Mixer with LO Buffer

3.3V SUPPLY AC ELECTRICAL CHARACTERISTICS (DOWNCONVERTER MODE,

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

(Typical Application Circuit with tuning elements outlined in Table 1, RF and LO ports are driven from 50I sources. Typical values

are at VCC = 3.3V, PRF = 0dBm, PLO = 0dBm, fRF = 3500MHz, fLO = 3200MHz, fIF = 300MHz, TC = +25NC, unless otherwise noted.)
