该论文提出了一种三频段无SAW滤波器的WCDMA/HSPA RF CMOS收发器，集成了可直接连接电池的片上DC-DC转换器，旨在降低3G射频子系统的物料成本。通过消除外部LNA和级间SAW滤波器，实现了低成本的全双工操作。

Full Duplex operation has so far necessitated external LNAs and inter-stage SAW filters in both Tx and Rx paths in commercial 3G phones. Recent publications, where techniques have been proposed to improve RF transceiver design, to enable Tx [1-5] or Rx [5-8] SAW filters to be removed, highlight the attention they now attract from the industry. Here we report a WCDMA transceiver (XCVR), complete with on-chip
