Abstract

A 3-chip, 6.5W CATV transmitter for video-on-demand applications is implemented in a 0.5/spl mu/m SiGe BiCMOS process. A 38dBmV IF input at 44MHz or 36.125MHz is upconverted to an output between 50 and 860MHz at a level adjustable between 41 and 58dBmV in <0.1dB steps. The 75/spl Omega/ input return loss is <-25dB and the 75/spl Omega/ output return loss is <-160. The wideband noise floor is <-80dBmV/Hz. Spurious signals in the CATV band are <-60dBc, and phase noise is <-88dBc/Hz at 10kHz offset.

用于有线电视视频点播系统的SiGe发射机芯片组

用于视频点播应用的3芯片6.5W有线电视发射机采用0.5/spl mu/m SiGe BiCMOS工艺实现。44MHz或36.125MHz的38dBmV中频输入上转换为50至860MHz的输出，电平在41至58dBmV之间可调，步进<0.1dB。75/spl ω /输入回波损耗<-25dB, 75/spl ω /输出回波损耗<-160。宽带本底噪声<-80dBmV/Hz。CATV频段的杂散信号<-60dBc，在10kHz偏移时相位噪声<-88dBc/Hz。
