StratEdge SMK/SMX packages are available in DC to 18 GHz and DC to 26GHz surface mount designs. Their leads are co-planar with their base. Unlike packages that are mounted in a hole in the circuit board, SMK/SMX packages mount directly on the board, reducing circuit board assembly costs. Surface mount packages also simplify the board layout and significantly reduce board design costs.
The SMK/SMX series incorporates a conductive metal base attached to an alumina ceramic ring frame. The base and the leads are attached using high temperature copper silver braze. These packages are sealed using a cup-shaped lid with a b-stage epoxy preform. The copper composite base is smaller and thinner than the bases in most ceramic package designs
SMK/SMX packages are very low loss from at frequencies as high as 26 GHz. This performance range makes them ideal for next generation test and measurement equipment, VSAT amplifiers, point-to-point and point-to-multipoint radios, and any high power application where surface mount packages are desired.
