The paper describes the key RF factors of UE (user equipment) for W-CDMA systems based on 3GPP specifications. The transmitter and receiver parameters are derived from the viewpoint of RF. In order for UE to retain high performance, the transceiver design requirements - such as ACLR (adjacent channel leakage power ratio), EVM (error vector magnitude), peak code domain error, spectrum emission mask for transmitter and reference sensitivity level, blocking characteristics, noise figure, ACS (adjacent channel selectivity), receiver AGC dynamic range - are considered. The UE transceiver is implemented and its performance requirements analysed through test scenarios.
