Abstract :
An integrated IF transmitter with on-chip synthesizer for W-CDMA application is presented. It was designed to comply with UMTS standard on a low cost application board. The 5-MHz ACLR is better than -60 dBc while output noise at maximum and minimum gain setting is -147 dBm/Hz and -167 dBm/Hz respectively, which is the minimum reported to date. Furthermore, the gain control curve linearity exceeds 3GPP requirements with a dynamic range higher than 80 dB.
