DIGITAL INTENSIVE RF RECEIVER |
摘要 |
PURPOSE: A digital intensive RF receiver is provided to perform per-narrow band noise shaping of desired band, thereby it is being favorable for digital design by removing necessity of a RF tuner, when IF(Intermediate Frequency) signal or frequency band signal centered by DC(Direct Current) is transformed through sub-sampling A/D transform. CONSTITUTION: A sub-sampling A/D(Analog to Digital) converter(400) transforms RF(Radio Frequency) signal of the second filter unit to digital signal according to sub-sampling clock of clock generation unit(300). In a A/D conversion process, the sub-sampling A/D converter divides the RF signal to a plurality of frequency bands. The sub-sampling A/D converter performs a plurality of noise shaping by sub channels in the RF signal. According to a system clock, a digital processing unit(500) processes the digital signal.
