High performances of shielded LTCC vertical transitions from DC up to 50 GHz

Embedded Microstrip Line to Stripline Vertical Transition Using LTCC Technique

“…The electromagnetic (EM) simulators use Maxwell equations to compute the response of a structure from its physical geometry. It can be applied to study complex 3D structures composed of linear and isotropic or anisotropic media [8]. This analysis method has great accuracy and presents attractive advantages to minimize computation time and provides better accurate results [9].…”

LTCC Fold-Back Bandpass Filter Designed With Capacitively Loaded Stubs

“…Generally, vias are highly utilized in vertical interconnection structures of high-density system-on-package substrates [23][24][25][26]. Field discontinuity may deteriorate the frequency response of filters when signals travel through vias, since the induced parasitic inductance behaves akin to a low-pass filter, attenuating high-frequency components.…”

Vertical Transition in Multilayer Millimeter Wave Module Using Circular Cavity

“…The distance between centre line of the aperture and circle centre d; the length of the stub l (calculated from centre line of the aperture); /4), h 0 = 2 mm, w 0 = 0.2 mm, R 0 = 1.6 mm, the transition structure was modeled with solid wall firstly and then the solid wall was replaced by vias-array under the guidelines of references [8][9][10][11], Some applications of SICC can be found in references [12][13][14], some important design guidelines can be found in [15][16][17][18][19]. The radius of the cavity R and the gap location d were two key parameters in designing of the transition structure; the R can be calculated with (3), and the parameter d was approximately λ g /4 ; the width of the microstrip lines were calculated to guarantee a 50 Ω impedance.…”
