WCDMA準(zhǔn)直接調(diào)制器，帶有VGA和PA驅(qū)動(dòng)器

MAX2395系列全集成單片準(zhǔn)直接調(diào)制器IC是針對(duì)WCDMA/UMTS發(fā)送器應(yīng)用設(shè)計(jì)的。與采用帶有IF VCO的IF SAW濾波器和IF合成器模塊相比，準(zhǔn)直接調(diào)制架構(gòu)可以降低系統(tǒng)成本，元件數(shù)量以及電路板空間。\n /MAX2395包括I/Q基帶濾波器、帶VGA的IF I/Q調(diào)制器、帶VCO的全集成PLL，上變頻混頻器，RF VGA以及功率放大器(PA)驅(qū)動(dòng)器。采用直接調(diào)制器方案可確保5% (典型值)的EVM和30dB (最小值)的載波抑制。RF VGA和IF VGA可提供90dB的標(biāo)稱輸出功率控制。無需外部本地振蕩器，即可實(shí)現(xiàn)高效的可變頻率偏置雙工器系統(tǒng)。\n 通過在SPI?/MICR \n? POUT = +6dBm時(shí)，EVM為5% \n? 1920MHz至1980MHz工作頻率(WCDMA TX) \n? +2.7V至+3.3V單電源工作 \n? 輸出功率為+6dBm時(shí)，工作電流為72mA \n? 81dB最小自動(dòng)增益控制(AGC)范圍 \n? 自動(dòng)ICC折返用于優(yōu)化功耗 \n? 無需IF SAW濾波器 \n? 片上RF PLL，帶有完全集成的VCO \n? 超低的外部元件數(shù);
