An RF front-end with an automatic gain control technique for a U/V band CMMB receiver
This paper presents a fully integrated RF front-end with an automatic gain control (AGC) scheme and a digitally controlled radio frequency varied gain amplifier (RFVGA) for a U/V band China Mobile Multimedia Broadcasting (CMMB) direct conversion receiver.The RFVGA provides a gain range ofS0 dB with a 1.6 dB step.The adopted AGC strategy could improve immunity to adjacent channel signal,which is of importance for CMMB application.The front-end,composed …查看全部>>
