This paper considers the design of a transceiver ableto provide a data rate of 10Gbps for the backhaul of the future mobile network. The paper describes a zero-IF architecture to support 64-QAM and a bandwidth of 2GHz in E-Band. Zero- IF architectures present several impairments that corrupt the information bearing base-band signal around DC. The paper reviews these issues paying special attention to the AC couplings in the transceiver analogue chain. This RF impairment is modeled at system level and its impact on transceiver performance is evaluated. The results presented in the paper highlight the importance of this RF impairment for high-order modulation. It is shown that the destruction of more than 0.01% of the signal in 64-QAM can yield an important loss in performance
