this paper presents the implementation of a four-order distributed band-pass filter. The band-pass filter based on LTCC technology is composed of four good performance resonators, each resonator is composed of three layers parallel strip-line, transmission zeros caused by Z strip-line achieve good stop-band attenuation through cross-coupling. By ADS circuit simulation and the HFSS software to optimize...
this paper presents the method of a s band wide-brimmed coupler. The coupler based on LTCC technology is composed of the strip-line horizontally, so as to realize higher coupling. By ADS circuit simulation and the HFSS software to optimize the 3D modeling, the measurement results of coupler match the electromagnetic simulation results, the center frequency of coupler is 3.1 GHz, the bandwidth is 900MHz,...
A high performance five-order band-pass filter based on LTCC technology was designed. The five-order band-pass filter is composed of five high-performance resonator, among which transmission zeros achieved good stopband attenuation through cross coupling. Software ADS and HFSS were used to optimize the simulation. Good agreements were found between the test and simulation results. The centre frequency...
