摘要

一种包含w波段压控振荡器的单片微波集成电路(MMIC)芯片。讨论了发射放大器、接收放大器、低噪声放大器和混频器。它被用作纯差FMCW雷达的前端，用于目标距离和距离速率传感应用。采用0.1 μ m假晶InGaAs-AlGaAs-GaAs - gaas HEMT工艺制备了6.9 mm × 3.6 mm的单片芯片。在90-94 GHz频率范围内，发射机输出功率大于10 dBm，最大调谐带宽为500 MHz。当输出发射功率为10dbm时，接收通道的转换增益为6db。基于单片机MMIC前端的竞争雷达系统进行了测试。计算的量程和量程率与实测数据吻合较好

A W-band single-chip transceiver for FMCW radar

A monolithic microwave integrated circuit (MMIC) chip containing a W-band voltage controlled oscillator (VCO). transmit amplifiers, a receiver low noise amplifier and a mixer is discussed. It is used as the front-end of a homodyne FMCW radar for target range and range rate sensing applications. The 6.9-mm*3.6-mm monolithic chip was fabricated using 0.1- mu m pseudomorphic InGaAs-AlGaAs-GaAs HEMT process technology. The transmitter output power is more than 10 dBm for frequencies in the range 90-94 GHz, and maximum tuning bandwidth is 500 MHz for the VO. The receiver channel has 6-dB conversion gain when the output transmitting power is 10 dBm. A compete radar system has been tested based on the single-chip MMIC front-end. The calculated range and range rate are in good agreement with the measurement data.<>
