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.
