ATC Q-BRIDGE THERMAL CONDUCTOR ATC Q-Bridge Thermal Conductor ATCs new Q-Bridge Thermal Conductor is manufactured with the highest quality materials for reliable and repeatable performance providing a cost effective thermal management solution. These devices are constructed with Aluminum Nitride (AlN) or Beryllium Oxide (BeO) and are available in standard EIA form factors. Q-Bridge provides the designer with the ability to manage thermal conditions by directing heat to a thermal ground plane, heat sink or any other specific thermal point of interest. The inherently low capacitance makes this device virtually transparent at RF / microwave frequencies. This device has the added benefit of offering Applications: additional layers of protection to adjacent components from hot spot thermal loads. GaN Power Amplifiers High RF Power Amplifiers Q-Bridge provides the benefit of increased overall circuit reliability. ATCs Q-Bridge is manufactured using one- Filters piece construction, providing a RoHS compliant SMT Synthesizers package that is fully compatible with high speed auto- Industrial Computers mated pick-and-place processing. It is available in various EIA case sizes. Custom configurations are also available.
