基地局用、低ノイズ、高リニアリティのSiGeミキサ
SUNNYVALE, CA-November 18, 2002-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX9993, the industry's highest performing, fully integrated SiGe mixer. The MAX9993 is specifically designed to meet the demanding requirements of any GSM/DCS/PCS/EDGE, iDEN™, PHS, and 3G wireless infrastructure systems. Contained on 1 integrated circuit, the MAX9993 delivers an outstanding IIP3 of 23.5dB, a conversion gain of 8.5dB, and an impressively low noise figure of 9.5dB.
Since the MAX9993 provides more than 8dB of conversion gain, the designer can eliminate a complete IF amplifier stage within the receiver lineup, saving cost and improving board yields. Concurrently, it replaces 2 amps, 2 baluns, an LO switch, plus dozens of other discrete components. Through this integration, the total board space used by the mixer is reduced by a factor of 4, and the discrete part count is reduced by 30%. Besides delivering performance that rivals the very best GaAs solutions, the MAX9993 provides the reliability and ESD robustness that only a silicon-based process (SiGe) can deliver.
The MAX9993 is ideal for GSM DCS/PCS, cdma2000™, WB-CDMA, and CDMA multicarrier and single-carrier base-station applications where high linearity and low noise are required for good bit error rate performance.
Superb IIP2 performance of >60dBm also eases receiver filtering requirements of close-in harmonics that can degrade error vector magnitude. On-chip RF and LO baluns and built-in matching circuits interface to 50Ω terminations.
Frequency hopping is supported with the high-isolation integrated LO switch with switching speeds of <50ns and >40dB of LO1-to-LO2 isolation. The on-board LO buffer provides tight drive-variance control, yielding a consistent G, NF, and IIP3 performance over temperature, supply, and input power.
The MAX9993 is available in a compact 5mm x 5mm 20-pin thin QFN. Prices start at $11.95 (1000-up, FOB USA).
