WCDMA准直接调制器，带有VGA和PA驱动器

MAX2395系列全集成单片准直接调制器IC是针对WCDMA/UMTS发送器应用设计的。与采用带有IF VCO的IF SAW滤波器和IF合成器模块相比，准直接调制架构可以降低系统成本，元件数量以及电路板空间。\n /MAX2395包括I/Q基带滤波器、带VGA的IF I/Q调制器、带VCO的全集成PLL，上变频混频器，RF VGA以及功率放大器(PA)驱动器。采用直接调制器方案可确保5% (典型值)的EVM和30dB (最小值)的载波抑制。RF VGA和IF VGA可提供90dB的标称输出功率控制。无需外部本地振荡器，即可实现高效的可变频率偏置双工器系统。\n 通过在SPI™/MICR \n• POUT = +6dBm时，EVM为5% \n• 1920MHz至1980MHz工作频率(WCDMA TX) \n• +2.7V至+3.3V单电源工作 \n• 输出功率为+6dBm时，工作电流为72mA \n• 81dB最小自动增益控制(AGC)范围 \n• 自动ICC折返用于优化功耗 \n• 无需IF SAW滤波器 \n• 片上RF PLL，带有完全集成的VCO \n• 超低的外部元件数;
