摘要：

A fully integrated dual-mode CMOS transceiver tuned to 2.4 GHz consumes 65 mA in receive mode and 78 mA in transmit mode from a 3-V supply. The radio includes all the receive and transmit building blocks, such as frequency synthesizer, voltage-controlled oscillator (WO), and power amplifier, and is intended for use in 802.11b and Bluetooth applications. The Bluetooth receiver uses a low-IF architecture for higher level of integration and lower power consumption, while the 802.11b receiver is direct conversion. The receiver achieves a typical sensitivity of -88 dBm at 11 Mb/s for 802.11b, and -83 dBm for Bluetooth mode. The receiver minimum IIP3 is -8 dBm. Both transmitters use a direct-conversion architecture, and deliver a nominal output power of 0 dBm, with a power range of 20 dB in 2-dB steps.
