SiGe, High-Linearity, 2000MHz to 3900MHz
Downconversion Mixer with LO Buffer
5.0V SUPPLY AC ELECTRICAL CHARACTERISTICS—fRF = 2300MHz TO 2900MHz,
LOW-SIDE LO INJECTION
(Typical Application Circuit with tuning elements outlined in Table 1, VCC = 4.75V to 5.25V, RF and LO ports are driven from 50Ω
sources. PLO = -3dBm to +3dBm, PRF = -5dBm, fRF = 2300MHz to 2900MHz, fIF = 300MHz, fLO = 2000MHz to 2600MHz, fRF > fLO,
TC = -40°C to +85°C. Typical values are for TC = +25°C, VCC = 5.0V, PLO = 0dBm, fRF = 2600MHz, fLO = 2300MHz, fIF = 300MHz, all
parameters are guaranteed by design and characterization, unless otherwise noted.) (Note 6)
