Abstract :
A multicarrier receiver, which is capable of receiving four parallel WCDMA channels, is described in this paper. The receiver is targeted for base-station applications and designed to drive high-resolution Nyquist-rate A/D converters. The multicarrier receiver achieves 2.6-dB / 3.0-dB NF at the WCDMA channels centered at 2.5 MHz and 7.5 MHz, respectively. The IIP3 for all four WCDMA channels is -12-dBm, and the receiver consumes 535 mW from a 2.5-V supply.
