Abstract :
The construction and electrical performance of a surface mount, thin-film, ceramic package are described. The package is fabricated on VIA/PLANETM, a ceramic substrate with hermetic tungsten-copper vias, in which the filled vias are used to form DC and 50 Ω RF ports. Vacuum-deposited, thin-film metal is photopatterned to achieve impedance control and desired electrical performance. Leads are brazed to the bottom of the substrate, directly onto the tungsten/copper vias, to form the surface mount package. Electrical performance of the package, up to 26.5 GHz, is reported. With the economics of array processing, this high-speed package is a low-cost, surface-mount alternative to co-fired technology
