Cirexx International have developed a module to demonstrate their ECLIPS technology. ECLIPS (Embedded Cooling Layer – Integrated Power System) is a system of producing high-power RF/microwave Printed Circuit Boards (PCBs) employing an embedded thermally engineered metalized heat-sink layer which has superior thermal conductivity characteristics and a very low-CTE.The Cirexx ECLIPS technology serves as an alternative to co-fired ceramics and hybrid integrated circuits. The item is essentially a common Printed Circuit Board, made from otherwise typical RF/microwave Printed Circuit Board materials and processes. But with a high thermal conductivity and very low CTE the user can mount very fine pitch devices and in fact direct attach/wire-bond bare die such as GaN and GaAs. The other electronic components on the board can be standard “plastic parts” attached in a standard process such as a vapor phase soldering. This combination results in an electronic board system that is smaller, lighter weight, easier to make revisions to and certainly much less costly than the ceramic hybrid, all-die alternative.The demonstration module allows Cirexx Application Engineers to demonstrate the technology at customer facilities and/or during ECLIPS presentations. With the use of common lab equipment the module demonstrates the efficient evacuation of heat generated by 2 bare die amplifiers and its effect on the power output.
