The MAX2023 is a low-noise, high-linearity, direct upconversion/downconversion quadrature modulator/demodulator designed for single and multicarrier 1500MHz to 2300MHz DCS 1800/PCS 1900 EDGE, cdma2000®, WCDMA, and PHS/PAS base-station applications.
The MAX2023 is a low‑noise, high‑linearity direct up‑conversion/down‑conversion quadrature modulator/demodulator designed for single‑ and multicarrier base‑station applications in the 1500 MHz to 2300 MHz range. It integrates passive mixers, LO drivers, baluns, and a phase splitter in a compact 36‑pin thin QFN package, reducing part count and power consumption.
Key features include a supply voltage of 4.75 V – 5.25 V, typical output power of +5.6 dBm, OIP3 of +23.5 dBm, IIP3 of +38 dBm, conversion loss of 9.5 dB, and a noise figure of 9.6 dB. The device offers extensive pin‑by‑pin descriptions, absolute maximum ratings, and recommended power‑supply bypassing techniques for optimal high‑frequency performance.
