This paper proposes a compact bandpass filter with excellent out-of-band performance. Stepped-impedance resonators (SIRs) are used to achieve an extended rejection bandwidth. Loaded stubs are also introduced to suppress the harmonic responses. The SIRs and the loaded stubs take up little extra room, and thus the proposed filter has a compact size. In this paper, a bandpass filter centered at 2 GHz...
A transmission-line bandpass filter based on bandstop filter is proposed in this paper. A key merit of the filter configuration is that the position of the transmission zeros can be conveniently controlled whereas the bandwidth is fixed. The bandpass filter consists of two half-wavelength resonators, two open circuited uniform impedance resonators and one stepped impedance resonator. With five reflection...
The matching of sensor and weapon system is important for the whole combat system. Combat system would have the optimum efficacy only if the indexes of sensor and weapon system attained to the best matching status. A method of optimization matching of sensor and weapon system based on geometric programming was given. This method means to construct a GP model, the target function of which would be...
