Summary: By multiplying with the continuous factor (CF), the conventional Class‐ F/F−1, Class‐J power amplifier (PA) can be expanded to their corresponding continuous modes, resulting in a great degree of freedom for broadband design. However, this method can hardly apply to other types of PAs. In view of this problem, the continuous mode is deeply analyzed from the perspective of equation solving for the first time, and a general theory for high‐efficiency broadband continuous PA design is proposed. In this theory, the continuous impedance space does not rely on a mapping relationship achieved by multiplying with the CF, but on a direct solution of the high‐efficiency equations to obtain the broadband design space. This approach is simpler and has the potential to provide greater design space. As a validation, this theory is used for the analysis of Class‐E PAs and a new continuous Class‐E (NC‐E) PA is presented. With knee‐point voltage and finite harmonics taken into account, this type of PA greatly expands the broadband design space of Class‐E PAs and also has the advantage of harmonic matching. The NC‐E PA is designed and manufactured using GaN HEMT CGH40010F, which achieves 40.6–41.6 dBm output power and 66.2%–74.2% drain efficiency (DE) in the frequency band of 2.5–3.8 GHz.

The steel roof of the West Stand structure in Jiangmen Sports Center is a super-span space steel tube truss arch structure. In this article, the simulation analysis, and construction monitoring process, and the arch foot deformation monitoring is researched systematically, and the fuzzy reliability analysis is established based on the construction monitoring process. The monitoring results show that the roof structure is in healthy state, and the arch foot deformation meets the design requirements, which means that detailed simulation calculation provides theoretical basis for construction monitoring, and the measured data agree well with the theoretical data. Reliability Fuzzy Comprehensive Evaluation of structural monitoring adopts a layered weighting method by dividing the entire structural monitoring into several types of key monitoring indicators, corresponding analysis is carried out according to the calculation formula of the weight of various indicators to solve the reliability problem of structural monitoring. It is shown through analysis that this method can provide an effective basis for on-site safety construction, and the above conclusions can provide references for related projects in the future.
