高集積化、一定グループディレイベクトル乗算器、コストを削減しACLRを改善
SUNNYVALE, CA-February 21, 2003-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX2045/MAX2046/MAX2047 family of highly integrated vector multipliers. The MAX204x family is specifically designed for the demanding requirements of GSM/DCS/PCS/EDGE, iDEN, PHS, cdma, and 3G linearized power amplifiers for cellular base stations.
These devices have a 12dB gain-control range and a 360° phase-control range. Gain and phase flatness performance is outstanding, yielding ±0.25dB and ±0.25°, respectively. Exceptional constant group-delay performance over a 260MHz control signal bandwidth yields improved ACLR performance. In addition, the MAX204x family provides the reliability and ESD robustness that only a silicon-based (SiGe) process can deliver.
With their high switching speed, these devices are tailored for both feed-forward and hybrid digital predistortion-based designs. An on-chip RF gain amplifier provides 8dB of gain, eliminating the need for an expensive external amp. To simplify interfacing, the MAX204x family has both current- and voltage-mode inputs.
The MAX2045/MAX2046/MAX2047 are packaged in a compact 5mm x 5mm 32-pin QFN. Prices start at $8.93 (1000-up, FOB USA).
