In this letter, a C-band compact wideband bandpass filter (BPF) with high selectivity and improved return loss (RL) is proposed. Two pairs of short-circuited stubs are employed on transmission-line model to generate three transmission poles two zeros (TZs), where the odd- even-mode analysis used analyze resonant frequencies BPF. By applying transversal signal-interference technique, additional TZs can be generated in upper lower stopbands, respectively. The measured results show that 3-dB...
Abstract A novel continuously tunable lowpass filter (LPF) with compact size, sharp roll‐off and low insertion loss is presented in this paper. The employs two varactor diodes, a pair of open‐ended coupled lines U‐shape step impedance line (SIL) an stub loaded at the center SIL to form very layout. odd‐ even‐mode analysis equivalent circuit model are demonstrated for estimation transmission characteristics. Tuning DC voltage applied on capacitance accordingly changes leading varying cutoff...
Abstract In this article, a pair of stub‐loaded interdigital hairpin resonators‐based filter with high group delay and improved stopband suppression is used to design an S‐band ultra‐low phase noise single‐ended oscillator. A transmission zero closed the edge passband in generated by introducing strong electric magnetic coupling, which can improve performance proposed low figure‐of‐merit (FOM) that considers both insertion loss feedback loop evaluate overall order verify concept, oscillator...
Load regulation and input voltage are the important parameters of DC-DC power supply.The quality them determines dynamic performance whole system.In order to improve two parameters, hysteresis current control strategy is studied some improvements made, not only inductor considered, but also capacitance charge balance cannot be ignored.A simulation model adopting improved based on Matlab/simulink constructed.The results indicate that supply posses good performance, verify correctness design.
The harmonic pollution of power electronic equipment has a strong negative effect on the quality supply and efficiency.In order to improve factor, we designed three-phase two-level active factor correction (APFC) circuit.The former Boost converter connected with input side rectifier realized (PFC).The post Buck function adjusting output voltage quickly corresponding control circuit.We carried out simulation in Matlab/simulink software environment.The results showed that current waveform is...
