High Linearity, Dual, SiGe Downconversion Mixer for 2.5G, 3G, and 4G Base Stations

Maxim Integrated Products introduces the MAX19985A 700MHz to 1000MHz, dual, downconversion mixer that integrates an LO switch, buffer, and splitter. Designed using Maxim's proprietary, monolithic SiGe process, this device delivers an unparalleled combination of linearity, noise performance, and component integration. This single IC provides two independent downconversion channels, each with a +25.5dBm (typ) IIP3, 8.7dB (typ) conversion gain, and 9.0dB (typ) noise figure. Additionally, the MAX19985A offers an industry-best 2LO-2RF spurious rejection of 76dBc for an RF level of -10dBm, and 71dBc for a level of -5dBm. The MAX19985A is designed specifically for 2.5G/3G/4G wireless-infrastructure applications in which high linearity and a low noise figure are critical for enhanced receiver sensitivity and blocker immunity.
