SiGe High-Linearity, 2000MHz to 3000MHz

Upconversion/Downconversion Mixer with LO Buffer

+5.0V SUPPLY AC ELECTRICAL CHARACTERISTICS

(DOWNCONVERTER OPERATION)

(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 = 2300MHz to 2900MHz, fIF = 300MHz, fLO = 2000MHz to 2600MHz, fRF > fLO,

TC = -40NC to +85NC. Typical values are for TC = +25NC, VCC = +5.0V, PRF = 0dBm, PLO = 0dBm, fRF = 2300MHz, fLO = 2300MHz,

fIF = 300MHz. All parameters are guaranteed by design and characterization, unless otherwise noted.) (Note 7)
