Leaded laminate copper-moly-copper base packages dissipates heat from high power compound semiconductor devices

The LL family of leaded laminate copper-moly-copper (CMC) base packages from StratEdge dissipates heat from high power compound semiconductor devices, such as gallium nitride (GaN), gallium arsenide (GaAs), and silicon carbide (SiC).


These packages handle applications through 6 GHz for use in RF radios for communications, radar, and high power millimeter-wave signals. The series includes two laminate power packages, both with a ratio of 1:3:1 CMC, which provides a good thermal match for alumina-based materials and a GaN chip. The LL802302 is 20.32x9.91mm wide with 2 leads and a raised lid with an epoxy seal. This is a flange package with a bolt hole on each end so the package can be bolted to the printed circuit board. The LL362302 is a flangeless, fully hermetic version of the LL802302 package, and has a flat ceramic lid. StratEdge offers both flange and flangeless styles to accommodate manufacturing processes to either bolt down or solder the package. Hermeticity is especially critical in aerospace and defense applications.

The SoCKIT evaluation kit is Arrow's latest development tool, featuring an Altera Cyclone V SoC with a dual-core ARM Cortex-A9 MPCore processor integrated within its 28nm FPGA fabric.

Altera SoCs allow embedded system developers to differentiate their end product with customized hardware and software, and extend the product lifecycle through hardware and software updates in the field. This month, Arrow Electronics is giving away five SoCKIT evaluation kits featuring Altera’s ARM-Based SoCs, worth €249 each, together with the free entrance to one of Arrow’s SoC workshops organized throughout Europe.


And the winners are...

In our previous reader offer, Freescale Semiconductor was giving away five IMX6Q, Sabre-lite kits, worth £128.06 each.

Lucky winners include Mr. X. Salada Sole from the UK, Mrs A. Peric from Germany, Mr Z. Janosy from Hungary, Mr D. Gacina from Croatia and Mr B. Boris from France. All should be receiving their packages soon. Let's wish them some interesting findings with their projects.
