Power amplifier plays a great important role in modern wireless communication system. In this paper, a class-AB power amplifier working in 2.11GHz–2.17GHz is designed and fabricated, tuned, measured. The measurement results show that the output power at 1dB compression point (P1dB) is 46.5dBm along with a drain efficiency of 36.9% at central frequency 2.14GHz. The upper TOI measured using a two-tone...
Hydrophobic ZnO self-cleaning thin films with the bionic micro-nano-bump-structures are prepared on ITO glass by growing ZnO nanoarrays supported by polystyrene spheres. The mechanism of the polystyrene spheres on ZnO nanoarrays structure formation is discussed and its superhydrophobic property is originated from the micro-nano-bump-structures of ZnO nanoarrays and surface roughness. Interestingly,...
The aim of this paper is to develop a novel method to separate Microthrix parvicella (M. parvicella) filaments from activated sludge easily and quickly, as there are a few difficulties in the isolation of M. parvicella filaments, such as complicated isolation process, time consuming, etc. In this work, a series of hydrophobic plate with and without microchannels have been prepared for the separation...
