[Abstract]:Indium phosphide high electron mobility transistor (InP HEMT) has the advantages of high electron mobility, excellent noise performance and good radiation resistance, so it is very suitable for making low noise amplifiers. Now it has gradually developed into a very competitive technology in the field of MMIC and even TMIC. This paper introduces the latest progress of terahertz monolithic low noise amplifier (LNA), briefly analyzes the device characteristics and related processes of InP HEMT, and briefly introduces the on-chip testing technology. It includes several commonly used two-port calibration techniques and two-port deembedding techniques. According to the in-chip test results, the small signal equivalent circuit model and the noise equivalent circuit model are established, and a terahertz monolithic low noise amplifier is designed. The design process includes the selection of circuit topology, the design of bias circuit and matching circuit, the simulation and optimization of circuit. Finally, the circuit layout. 2 is determined under the layout adjustment rule. THz monolithic low noise amplifier (LNA) is fabricated by using the 0. 1 渭 m InP HEMT process developed in China, and the results are tested and analyzed. Under the VDX 1.7V VGG 0V bias condition, the small signal gain of the LNA is greater than 5 dB in 101.3~106.1GHz, and the maximum gain is 7.007 dB at 104GHz. The input and output echo loss is better than -5 dB. Although there is a certain gap between the measured results of the circuit and the design index, a breakthrough attempt has been made in the research of terahertz InP HEMT monolithic low noise amplifier using the independent process technology. The research of this subject has important practical significance to improve the whole level of our country in the field of terahertz technology, narrow the gap with the leading level of foreign countries, and break the technology blockade of developed countries to our country.
