摘要： LTCC coupled stripline resonator filters for use as bandpass filters are implemented with combline topology or with interdigital topology. The filter bandwidths range from about 0.3 GHz to about 4.5 GHz, or higher, depending of the manufacturing limitations with frequency operation of about 0.1 GHz to about 100 GHz. The filters have a plurality of through plated vias extending through the filters and connecting the top and bottom ground layers to form electric walls thereby reducing the coupling between the adjacent resonators.

摘要： An RF circuit includes a first dielectric material, a signal line and a bias line over a first surface of the first dielectric material, a conductive layer over a second surface of the first dielectric material, and a second dielectric material over the conductive layer. The first and second dielectric materials have different dielectric constants. The conductive layer includes a ground plane over which the signal line is formed. A conductive material void, with which a section of the bias line is aligned, is present in the second conductive layer. The RF circuit further includes a mounting area for an RF device. First ends of the signal line and the section of the bias line are located proximate to the mounting area to enable the signal line and the bias line to be electrically coupled with one or more leads of the RF device.

摘要： The invention presents a LTCC balun filter using two out-of-phase filtering circuits. The LTCC balun filter is comprised of three half-wavelength resonators and grounds which are located on fourteen metal layers. Vias are utilized to connect different metal parts. The first, fourth, seventh, eleventh and fourteenth metal layers are the ground. The three half-wavelength resonators are on the second, third, fifth, sixth, eighth, ninth, tenth, twelfth and thirteenth metal layers. By adjusting the coupling parts of the three half-wavelength resonators, namely the lengths of the seventh, eighth, ninth, tenth and eleventh layers, as well as the distances between them, the coupling strength between the half-wavelength resonators can be tuned. In addition, the quality factor of the circuit can be improved by tuning the port positions. By using the multi-layer LTCC technology, the present invention has the advantage of compact size, novelty, creativity and practicability.
