Sandia National Labs Renders Temperature-Stable Circuits

Sandia National Laboratories has come up with a unique approach to handle materials mostly employed in microelectronics circuits, like ones used in cell phones. This approach expiates the changes due to temperature fluctuations, as they affect the temperature coefficient of resonant frequency, a key characteristic of materials used in radio and microwave frequency applications. This work was put through the just completed two-year Early Career Laboratory Directed Research and Development (LDRD) project, where the main aim was understanding the behavior of certain materials, the knowledge of which could help manufacturers develop much better products. Also, manufacturers could cut down prices by getting rid of additional mechanical and electrical elements to counterbalance the temperature fluctuations.

Steve Dai, researcher at Sandia National Laboratories, operated over low-temperature co-fired ceramic (LTCC), a multilayer 3-D packing and interlinking technology that can merge the passive elements like resistors, capacitors and inductors. Presently, the focus is on whether this technology is practical, whether a device could be developed using it, and whether it will be reliable.
