This paper presents the design and simulation result of a miniaturized millimeter-wave bandpass filter realized by low temperature co-fired ceramic (LTCC) technology. The bandpass filter with a central frequency of 60 GHz and a 6 GHz pass-band is designed as a three-dimensional (3-D) structure based on distributed components. A distinct feature of this filter is the smaller size and lower in sertion...
We demonstrate a 10GHz fs-pulse train by external repetition rate multiplication in four phase-tunable Mach-Zehnder interleavers implemented in planar waveguide technology. A minimum RF suppression ratio of −27dB can be achieved with thermal tuning.
To solve the parameter tuning difficulties of auto-disturbance-rejection controllers for induction-motor frequency control system, the paper proposes a parameter optimization method based on variable-metric chaotic strategy. The new scheme could effectively settle the issues of an auto-disturbance-rejection controller, such as the widely dispersed, interactional multi-parameters and difficult of coordinated...
