A compact broadband high-power limiter is proposed in this paper. The limiter has a two stages structure which composed of different PIN diodes. A broadband LC impedance transformation network is employed in limiter to replace traditional quarter-wavelength line. This limiter has smaller size and higher isolation compared with traditional one in low frequency. To verify proposed structure, a limiter...
Based on the burning mechanism of the device, novel clipper circuit is introduced to the design of LNA. The clipping diodes were placed in parallel with the gate of transistor, and absorbed into the input matching circuit of LNA. Finally, the influence of the characteristic impedance of series microstrip in input matching circuit on the anti-burnout performance of LNA is discussed. The results of...
In this paper, an ultra-wideband (UWB) band-pass filter (BPF) for wireless communications is proposed. The band-pass filter consists of a stepped impedance resonator (SIR) with input-output cross-coupling. Additional rectangle-slot defected ground structure (DGS) is employed to improve the attenuation performance in the stop band and generate a strong coupling improving the pass-band property of the...
Previous studies demonstrated that cancer sera contain antibodies, which react with a unique group of autologous cellular antigens called tumour‐associated antigens (TAAs). This study determines whether a panel of TAAs would enhance antibody detection and be a useful approach in pancreatic cancer (PC) detection and diagnosis. The panel of TAAs was composed of six TAAs including p53, p16, p62, survivin,...
