摘要

提出了一种符合IEEE 802.11ah标准的射频收发器，具有直接转换接收器和全数字极性发射器。对于接收器，电流模式射频前端覆盖755MHz至928MHz的全球强制模式。数字辅助模拟基带通过自动增益/直流偏置校准实现可变增益和带宽。该接收器采用40nm CMOS和1V电源实现，在1MHz MCS0模式(即300kbp/s)下实现- 104dBm灵敏度。它满足相邻信道抑制要求，余量至少为17dB。数字极极发射机实现了−31dB的EVM和10dB的频谱掩模裕度。

A 4mW-RX 7mW-TX IEEE 802.11ah fully-integrated RF transceiver

An IEEE 802.11ah-compliant RF transceiver with a direct-conversion receiver and a fully-digital polar transmitter is presented. For the receiver, a current-mode RF front-end covers the mandatory modes worldwide from 755MHz to 928MHz. The digitally-assisted analog baseband achieves variable gains and bandwidths with an automatic gain/DC-offset calibration. Implemented in 40nm CMOS with 1V supply, this receiver achieves −104dBm sensitivity in the 1MHz MCS0 mode (i.e., 300kbp/s). It fulfils the adjacent channel rejection requirements with at least 17dB margin. The digital polar transmitter achieves −31dB EVM and 10dB spectral mask margin.
