摘要： A direct conversion satellite tuner is fully integrated on a common substrate. The integrated tuner receives an RF signal having a plurality of channels and down-converts a selected channel directly to baseband for further processing. The integrated tuner includes on-chip local oscillator generation, tunable baseband filters, and DC Offset cancellation. The integrated tuner can be implemented in a completely differential I/Q configuration for improved electrical performance. The entire direct conversion satellite tuner can be fabricated on a single semiconductor substrate using standard CMOS processing, with minimal off-chip components. The tuner configuration described herein is not limited to processing TV signals, and can be utilized to down-convert other RF signals to an IF frequency or baseband.

摘要翻译： 直接转换卫星调谐器完全集成在公共基板上。 集成调谐器接收具有多个信道的RF信号，并将所选择的信道直接下变频到基带用于进一步处理。 集成调谐器包括片上本地振荡器产生，可调谐基带滤波器和DC偏移消除。 集成调谐器可以以完全差分的I / Q配置来实现，以改善电气性能。 整个直接转换卫星调谐器可以使用标准CMOS处理在单个半导体衬底上制造，具有最小的片外部件。 这里描述的调谐器配置不限于处理TV信号，并且可以用于将其它RF信号下变频到IF频率或基带。
