SiGe, High-Linearity, 2300MHz to 4000MHz
Upconversion/Downconversion Mixer with LO Buffer
5.0V SUPPLY AC ELECTRICAL CHARACTERISTICS (DOWNCONVERTER MODE,
fRF = 2300MHz to 2900MHz, HIGH-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 = 5.0V, PRF = 0dBm, PLO = 0dBm, fRF = 2600MHz, fLO = 2900MHz, fIF = 300MHz, TC = +25NC, unless otherwise noted.)
