    Abstract

    A base-station receiver, which is capable of receiving from one to four adjacent WCDMA channels, is described in this paper. The receiver is designed to drive a high-resolution Nyquist-rate A/D converters and it can be used as a direct-conversion receiver (DCR) or as an low-IF receiver in WCDMA bands I-III. The low-IF NF is 2.7 / 3.0 dB for the channels centered at 7.5 MHz and 2.5 MHz, respectively. The measured IIP3 of the receiver varies from -10 dBm to -8 dBm depending on the number of the received channels. The power consumption is 542.5 mW from a 2.5-V supply.
