tured 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
additional layers of protection to adjacent components
from hot spot thermal loads.
Q-Bridge provides the benefit of increased overall cir-
cuit reliability. ATC’s Q-Bridge is manufactured using
one-piece construction, providing a RoHS compliant
SMT package that is fully compatible with high speed auto-
mated pick-and-place processing. It is available in various
EIA case sizes. Custom configurations are also available.
Applications:
• GaN Power Amplifiers
• High RF Power Amplifiers
• Filters
• Synthesizers
• Industrial Computers
• Switch Mode Power Supplies
• Pin & Laser Diodes
Features:
• High Thermal Conductivity
• Low Thermal Resistance
• Low Capacitance
