RF communications and radar systems are comprised of tightly packaged high wattage components requiring a controlled temperature to meet performance and reliability parameters. As these systems are becoming smaller and more powerful, existing thermal management technology limits system performance. An approach being pursued to address thermal management issues is localized synthetic jet die-level...
RF communications and radar systems present an extreme thermal management challenge. These systems are comprised of tightly packaged high wattage components requiring a controlled temperature to meet performance and reliability parameters. One approach being pursued to meet this thermal challenge is embedding piezoelectric actuators within the electronics to create synthetic air jet drives for localized...
Thermal management is challenging in RF communication and radar systems that require high-power levels for operation and reliability as well as small footprints to control intrinsic losses and meet design constraints. An interesting approach uses discrete, in-situ fluid handling and embedded synthetic jet drivers to enhance local cooling at the component. In this approach, fluid cavities and actuators...
The Aviation and Missile Research, Development and Engineering Center has been involved in an Army Technology Objective (ATO) aimed at furthering phased arrays for both tactical seekers and communication links.1'2 The ATO has been pursuing both MicroElectroMechanical Systems (MEMS) and MMICbased phase shifters with an overall goal of of reducing missile seeker costs by 50% based on the missile mission...
