Abstract: A hierarchical proxy deployment method includes: performing information collection and information interaction in a hierarchical proxy deployment architecture to obtain bandwidths and latencies of all inter-node communication links; and selecting an optimal proxy deployment solution from all feasible proxy deployment solutions based on the bandwidths and latencies of all the inter-node communication links. According to the method, a hierarchical proxy deployment architecture is used. An optimal proxy deployment solution is formed by selecting the optimal location and the optimal number of proxies for deployment to meet the transmission performance requirement of network applications in 5G/B5G networks. Therefore, transmission performance requirements are satisfied by a proxy deployment with a minimized number of proxies, thereby reducing network overheads and resource waste.

Abstract: The present disclosure provides a GaAs monolithic integrated terahertz low-noise communication system transceiver front-end, including an intermediate frequency circuit and a terahertz circuit. The terahertz circuit includes a local oscillator frequency tripler, a local oscillator unidirectional 3 dB filter coupler, a radio frequency 180° filter coupler, and two terahertz GaAs monolithic integrated subharmonic mixers. The local oscillator unidirectional 3 dB filter coupler and the radio frequency 180° filter coupler each include one ring-cylindrical resonant cavity and four rectangular waveguides. The ring-cylindrical resonant cavity is divided into four rectangular waveguides which are correspondingly connected to the four sector-annular resonant cavities, respectively. The present disclosure suppresses the local oscillator noise by adopting a local oscillator unidirectional 3 dB filter coupler and a radio frequency 180° filter coupler with both coupling and filtering functions, thereby achieving a low local oscillator noise transceiver front-end.

Abstract: The invention belongs to the field of electronic ceramics and its manufacturing, in particular to the modified NiO-Ta2O5-based microwave dielectric ceramic material sintered at low temperature and its preparation method. It is guided by ion doping modification, not only considering the substitution of ions with similar radius, such as Zn2+ replacing Ni2+ ions, V5+ replacing Ta5+ ions; Meanwhile, the selected doped oxide still has the property of low melting point. Therefore, the microwave dielectric properties of NiO-Ta2O5-based ceramic material can be improved and the appropriate sintering temperature can be reduced. In the invention, by adjusting the molar content of each raw material, the NiO-Ta2O5-based ceramic material with low-temperature sintering, stable temperature and excellent microwave dielectric property is directly synthesized at one time, which can be widely applied to the technical field of LTCC.

Abstract: A DC-DC converter circuit with selectable working modes is disclosed. Compared with the traditional chip that works in one mode, the DC-DC converter with selectable working modes adds only a mode selection circuit, so that the chip can work in voltage control mode or current control mode. On the one hand, the applications of the chip are more extensive, and on the other hand, when the applications are different, the cost of developing a DC-DC converter with selectable working mode is greatly reduced compared with the traditional DC-DC converter.
