Abstract

This paper reports the first W-band monolithic single sideband FMCW transceiver with direct digital synthesizer modulation. This heterodyne transceiver improves the system sensitivity over the previously reported homodyne approach. The complete transceiver has better than 12-dB suppression of the image sideband with a nominal LO drive of 9 dBm and is estimated to exhibit a 11-dB noise figure for IF as low as 1 MHz. This MMIC chip was fabricated using TRW production line process and is suitable for automotive radar applications.
用于汽车雷达的w波段单片单边带收发器
本文报道了首个采用直接数字合成器调制的w波段单片单边带FMCW收发器。这种外差收发器比以前报道的外差方法提高了系统灵敏度。完整的收发器对图像边带的抑制优于12 db,标称LO驱动器为9 dBm,并且估计在中频低至1 MHz时显示11 db的噪声系数。该MMIC芯片采用TRW生产线工艺制造,适用于汽车雷达应用。
