MAX2042A
SiGe High-Linearity, 1600MHz to 3900MHz
Upconversion/Downconversion Mixer with LO Buffer
5.0V Supply, RF = 2000MHz to 2900MHz, HIGH-SIDE LO INJECTION AC ELECTRICAL
CHARACTERISTICS (DOWNCONVERTER OPERATION) (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 = -6dBm to +3dBm, PRF = 0dBm, fRF = 2000MHz to 2900MHz, fLO = 2300MHz to 3200MHz, fIF = 300MHz,
fRF < fLO, TC = -40NC to +85NC. Typical values are for TC = +25NC, VCC = 5.0V, PLO = 0dBm, fRF = 2600MHz, fLO = 2900MHz,
fIF = 300MHz.) (Note 7)
