StratEdge Corporation has released its SMK Series surface mount DC to 26 GHz packages for test and measurement, VSAT, point-to-point, point-to-multipoint, and WiMax applications. These power packages have low insertion loss, good return loss, and excellent thermal properties.
The SMK Series ceramic packages were designed to provide good electrical transition performance for die in the DC to 26 GHz range. See the s-parameter plot below displaying the 580495 package performance. The packages are made to provide wideband electrical performance and incorporate copper composite bases for enhanced thermal dissipation. These are true surface mount packages that allow automated assembly and soldering for high volume production of devices without sacrificing electrical and thermal performance. They are sealed with cup-shaped liquid crystal polymer lids with B-stage epoxy preforms that are provided with the lids.
"Plastic packages can't handle the heat produced by die with high power dissipations," said StratEdge vice president of Global Sales Casey Krawiec. "Our SMK series can handle both the thermal and electrical requirements of these devices and can be used in many high frequency applications because of their wideband performance. Our customers who have used them are extremely pleased with their performance and the convenience of them being surface mount."
