The direct conversion receivers have advantages of low lost, low power dissipation and high integration, so their application has been getting widely attention. This paper gives an introduction of DCR theory, focuses on the key technology problems of DCR such as DC offset, I/Q mismatch, even-order distortion and so on. The solution to the problems is also given in the paper. The paper provides an analysis of the effect of RF front end on the performance of DCR. In the last, the performance of DCR is simulated through ADS. (4 pages)
