The MAX2039 high-linearity passive upconverter or downconverter mixer is designed to provide 7.3dB NF and a 7.1dB 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 +34.5dBm and +33.5dBm 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-pincompatible mixer meant for high-side LO injection, contact the factory.)
