Abstract

A balanced HEMT mixer for 76-77 GHz car radar applications has been designed and fabricated on a 6 inch GaAs production line. The monolithic circuit has a very small chip size of only 0.56 mm/sup 2/. With 2 dBm of LO power, a conversion loss below 11 dB was measured in the 76-77 GHz band. The results demonstrate that the single-device concept used in the circuit design is suitable for very compact monolithic millimeter-wave mixers.

单片共面77 GHz平衡HEMT混频器，芯片尺寸非常小

在6英寸GaAs生产线上设计并制造了一种用于76-77 GHz汽车雷达应用的平衡HEMT混频器。该单片电路的芯片尺寸非常小，仅为0.56 mm/sup /。当本端功率为2 dBm时，在76-77 GHz频段测量到的转换损耗低于11 dB。结果表明，电路设计中采用的单器件概念适用于非常紧凑的单片毫米波混频器。
