当前位置：MAX19985A - Highest Linearity, Dual, SiGe Downconversion Mixer for 2.5G, 3G, and 4G Base Stations
发布时间：2008-11-05 浏览：4095次
- The MAX19985A is a fully integrated, dual, downconversion mixer with an on-chip LO switch, buffer, and splitter.
- This device delivers an unparalleled combination of linearity, noise performance, and component integration.
- To achieve these benchmarks, the MAX19985A is designed using a proprietary, monolithic SiGe process that has been optimized for high linearity.
- Designed specifically for 2.5G/3G/4G wireless-infrastructure applications, the MAX19985A is ideal for LTE, WiMAX™, GSM/EDGE, WCDMA, and cdma2000® wideband applications.
As a complete SiGe downconverter, the MAX19985A integrates two state-of-the-art mixer cores; four amplifiers; three baluns; an LO switch, buffer, and splitter; and dozens of discrete components. The device's 8.7dB conversion gain enables the elimination of a complete IF amplifier stage within the receiver lineup. The MAX19985A's outstanding 2LO-2RF performance can also ease the filtering requirements of close-in harmonics, thus leading to simpler and more cost-effective filter designs. Due to integration of this functionality and performance into one monolithic design, this mixer is half the size of comparable discrete solutions and reduces the total part count by 45%.
The MAX19985A is packaged in a compact, 6mm x 6mm, 36-pin TQFN that is pin compatible with the MAX19995*/MAX19995A* series of 1700MHz to 2200MHz dual mixers, and pin similar to the MAX19997A*/MAX19999* series of 1850MHz to 3900MHz dual mixers. This family of downconverters is ideal for applications in which a common PCB layout is used for multiple frequency bands. Prices start at $9.96 (1000-up, FOB USA).
