The MAX2039 is a high-linearity passive upconverter or downconverter mixer designed to provide 7.3 dB NF and a 7.1 dB conversion loss for an RF frequency range of 1700MHz to 2200MHz to support UMTS/WCDMA, DCS, and PCS base-station transmitter or receiver applications. The IIP3 is typically +34.5 dBm and +33.5 dBm for downconversion and upconversion operation, respectively. With an LO frequency range of 1500MHz to 2000MHz, this particular mixer is ideal for low-side LO injection architectures. (For a pin-to-pin-compatible mixer meant for high-side LO injection, contact the factory.)
The MAX2039 is a passive upconverter/downconverter mixer designed for UMTS/WCDMA, DCS, PCS, and other base‑station applications. It offers a 7.3 dB noise figure, 7.1 dB conversion loss, and high linearity with IIP3 around +34.5 dBm.
The device is supplied in a compact 20‑pin thin QFN‑EP package (5 mm × 5 mm) and operates from a 4.75 V‑5.25 V supply with a typical supply current of 135 mA. Integrated features include a double‑balanced mixer core, LO buffer, SPDT LO switch, and on‑chip baluns for single‑ended RF and LO ports.
