MAX2042A
SiGe High-Linearity, 1600MHz to 3900MHz
Upconversion/Downconversion Mixer with LO Buffer
3.3V Supply, RF = 2000MHz to 2900MHz, HIGH-SIDE LO INJECTION AC ELECTRICAL
CHARACTERISTICS (DOWNCONVERTER OPERATION)
(Typical Application Circuit with tuning elements outlined in Table 1, RF and LO ports are driven from 50I sources, Typical values
are for TC = +25NC, VCC = 3.3V, PRF = 0dBm, PLO = 0dBm, fRF = 2600MHz, fLO = 2900MHz, fIF = 300MHz, unless otherwise noted.)
