摘要

This paper looks at a new 77GHz adaptive cruise control (ACC) radar transceiver design, which has placed considerable emphasis on low parts count, ease of assembly and test, excellent performance over temperature and ease of system integration. Unlike the currently available 77GHz transceivers, which use either a cavity Gunn diode voltage controlled oscillator (VCO) or a monolithic microwave integrated circuit (MMIC) chip set for the signal source, this unit uses a novel graded gap Gunn diode (G3D) planar VCO technology. This approach is inherently low cost as the 77GHz oscillator is assembled into the module as a small (10xlOx4mm), hermetically packaged device. The millimetre wave section of the module was built on low dielectric constant softboard, which fits into a metal housing, which is 50 x 45 x 15mm excluding the waveguide feed. The operation and fabrication of the Gunn diode is discussed as well as a description of the physics behind a frequency modulated continuous wave (FMCW) radar sensor.
