Up- and down-converter chip set for LMDS using three-dimensional masterslice MMIC technology

Three-dimensional masterslice MMIC technology enables quick development of MMICs. This paper discusses miniature mixers and amplifiers for LMDS up- and down-converters. An even-harmonic mixer, a resistive mixer, a balanced-resistive mixer, and amplifiers were developed using newly designed master arrays. These circuits cover the LMDS band and can be easily integrated into a single chip to build a highly integrated multifunctional MMIC in a very short turn-around-time.
