GENERAL DESCRIPTION The AD7011 is a complete low power, CMOS, π/4 DQPSK modulator with single +5 V power supply. The part is designed to perform the baseband conversion of I and Q transmit waveforms in accordance with the American Digital Cellular Telephone system (TIA IS-54). FEATURES Sin

CMOS ADC pi/4 DQPSK基带发射端口

AD7011是一款完整的低功耗、CMOS、pi/4 DQPSK调制器，采用+5 V单电源供电，设计用于根据美国数字蜂窝电话系统标准(TIA IS-54)执行I和Q发射波形的基带转换。\n\n片内pi/4差分正交相移键控(DQPSK)数字调制器包括平方根升余弦滤波器，用于响应发射数据流而产生I和Q数据。AD7011还包括斜坡控制包络逻辑，用于在发射突发脉冲开始或结束时的上斜坡或下斜坡对I和Q输出波形进行整形。\n\n除了提供pi/4 DQPSK调制所需的全部逻辑以外，该器件还提供重构滤波器来获得平滑的DAC输出，从而提供连续时间模拟输出。针对I和Q信号，AD7011均产生差分模拟输出。\n\n所
