Pioneering semiconductor technology since 1998

In 1998, Dr. K.H. Lee planted the first seed of GCT Semiconductor (GCT) with the development of a new version of the direct conversion architecture for RF transmission and reception functionality. The goal was to create an architecture that could be tailored to suit the demands of a variety of wireless applications while still taking advantage of the manufacturing yields, high level of integration and cost benefits of CMOS manufacturing processes.

Dr. Lee developed GCT's Direct Conversion CMOS RF technology, and founded GCT Semiconductor in 1998.
