In this paper, it introduces some new developments of several new LTCC microwave stereo integrated circuits, including: X-band ultra wideband balun, ultra wideband 3dB orthogonal directional couple, a new bandpass filter with highly steep band, ultra-wideband and palanar magtic T, bandpass filter with double transmission zeros, quintuple-mode dual-band filter, ultra broadband vivaldi antenna with...
In this paper studies an X-band ultra-wideband micro-balun based on LTCC, the working frequency of 7–13GHz, belonging to the X-band, the relative bandwidth is 60%. In this paper, from the design and manufacture of the product, combined with the theoretical basis, through the HFSS simulation software to complete the design, finally, it decided to use three coupling lines to improved Marchand Balun...
In this paper, an ultra-wideband stripline 3dB orthogonal directional coupler based on LTCC is studied. The operating frequency is 0.5–3.5GHz and the relative bandwidth is 150%. The difficulty lies in the requirements of ultra-wideband, high performance and miniaturization. In this paper, we started from the design and manufacture of the product, combined with the theoretical basis, through the HFSS...
This letter outlines the design and manufacture of a UHF-band miniaturized band-pass filter realized by low-temperature cofired ceramic (LTCC) technology for super heterodyne microwave receiver applications. A distinct feature of this filter is the smaller size than conventional filter at such a low frequency and steady pass-band temperature electrical performance compared with surface acoustic wave...
A low-temperature-cofired ceramic (LTCC) bandpass filter with low insertion loss and high image rejection is presented for super heterodyne microwave receiver within 6.5-7.1 GHz band. By improving the filter cell structure, two transmission zeros can be generated to achieve wide-band image suppression from cascading filter cells. The presented method provides the design flexibility of locating these...
