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.

Abstract: The present disclosure discloses an adaptive high-precision compression method and system based on a convolutional neural network model, and belongs to the fields of artificial intelligence, computer vision, and image processing. According to the method of the present disclosure, coarse-grained pruning is performed on a neural network model by using a differential evolution algorithm first, and the coarse-grained space is quickly searched through an entropy importance criterion and an objective function with good guidance to obtain a near-optimal neural network structure. Then fine-grained search space is built on the basis of an optimal individual obtained from the coarse-grained search, and fine-grained pruning is performed on the neural network model by a differential evolution algorithm to obtain a network model with an optimal structure. Finally, the performance of the optimal model is restored by using a multi-teacher multi-step knowledge distillation network to reach the precision of an original model.
