The SMX Series ceramic packages were designed to provide good electrical transition performance for die in the DC to 18GHz range, although they have been used and performed well in applications beyond 18GHz.
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 packages.
Tests on the StratEdge SMX 580447 package were performed by Brian Higgins, RF Developmental Engineer, of JDS Uniphase, Bloomfield, Connecticut.
A 50ohm through line was mounted inside the StratEdge package with conductive epoxy.
Double 1mil diameter gold wires were used to connect the line to the package at the input and output.
Adjacent package traces were grounded to the package base to prevent the signal from coupling.
Test results showed that insertion loss was better than -1.5dB up to 14GHz and better than -2.25dB through 18GHz.
The measured results are the combined losses from two package transitions, two sets of wire bonds, and the 50ohm thru line.
"Plastic packages can't handle the heat produced by die with high power dissipations", said StratEdge Vice President of North American Sales Casey Krawiec.
"Our SMX series can handle both the thermal and electrical requirements of these devices and can be used in many, many high speed and high frequency applications because of their wideband performance".
"Our customers who have used them are extremely pleased with their performance".
