General Description

The MAX2043 high-linearity passive upconverter or downconverter mixer is designed to provide approximately +31dBm of IIP3, +67dBc of LO ± 2IF spurious rejection, 7.8dB of noise figure, 7.5dB of conversion loss, and -52dBm of LO leakage for UMTS/WCDMA, DCS, PCS, and WiMAX base-station applications. With a 1700MHz to 3000MHz RF frequency range and a 1900MHz to 3000MHz LO frequency range, this mixer is ideal for high-side LO injection architectures.
