摘　　要：本文提出了一种适用于IEEE 802.15.4标准的2.4GHz免认证ISM频段的全集成CMOS射频收发机.接收机采用低中频结构以降低功耗、提高灵敏度,发射机则采用直接上变频结构以降低设计复杂度和功耗.芯片采用0.18μm 1P4M CMOS工艺以及MIM电容制造,供电电压1.8V.测试结果显示,在误包率为1%时,接收机灵敏度达到了-97d Bm,发射机输出至100Ω差分天线端口的最大输出功率为+3d Bm.接收模式和发射模式下的电流功耗分别为17m A和19m A,芯片面积3.3mm×2.8mm.A highly integrated CMOS transceiver was presented for 2.4GHz unlicensed 1SM （Industrial, Scientific and Medical） band compatible to the IEEE 802.15.4 Standard. Low-IF topology was adopted in the receiver for low power consumption and high sensitivity while direct up-conversion in transmitter for low complexity. The lransceiver chip has been fabricated in a 0.18μm 1P4M CMOS （Complementary Metal Oxide Semiconductor） technology with MIM （Metal-Insulator-Metal） capacitors and supplied by a single 1.8V. The experimental results show that the receiver achieves a sensitivity of - 97dBm for PER（Packet Error Rate） of 1% and the transmitter provides a max power output of ＋ 3dBm into 1000 differential antenna port. This transceiver dissipates 17mA in receive mode and 19mA in Iransrnit mode and occupies an area of 3.3mm×2.8mm.
