Researches of UWB MMIC control circuits and LTCC 3D integrated circuit technology

Abstract

This paper introduces the research results of the GaAs ultra-wideband MMIC control circuit technology, including: ultra-wideband digital phase shifter, digital attenuator, absorption type switch, reflective switch and vector modulator. The research results of three-dimensional integrated circuit technology based on LTCC are also proposed in this paper, including a variety of LTCC bandpass filters, lowpass filters, highpass filters, duplex devices, power dividers, baluns and couplers. Especially, It is discussed the design ideas and methods of the above circuit in details.
