Description

Research Topic Description, including Problem Statement:

Power and thermal management of Radio Frequency (RF) electronics and Electronically Steered Arrays (ESA) requires improvement to support Size, Weight, and Power (SWaP) constrained platforms. Energy storage (power time product) available for these platforms demands energy-usage strategies with reconfigurable RF and digital electronic technologies. Research is needed to identify, design, and control RF and digital electronics in order to adaptively control the RF-digital channel as a function of power. One key aspect to viable power management is to rapidly recover the RF and digital channel fidelity when transitioning from power-off to power-on states or less to more resources. Key RF and digital components to be investigated are: low-noise and power amplifiers (LNAs, PAs), RF tuners, Analog to Digital Converters (ADC), and digital channelizers. Power requirements depend upon the specific application being performed; such as: receive mode (single-input or multiple inputs) versus transmit mode (single or multiple outputs). Additionally, the electronic density required for a two-dimensional ESA unfortunately increases as the square of the highest RF collected. An increase in ESA electronics requires proper power and thermal design, as well as, novel management techniques, specifically for ESAs operating in millimeter wave frequencies on SWaP constrained platforms.

 

Example Approaches:

  • Research RF component designs that can be dynamically reconfigured to save power or boost performance. This could include powering off devices not in use, boosting power for better gain, applying or removing RF Interference canceling resources, variable sample rate and resolution of ADC designs, and performance adjustments of digital channelizers.
  • Research a hybrid of analog and digital beamforming stages to reduce ESA DC-power density
  • Research methods of thermal management of mmW ESAs
  • Research alternative technologies to improve thermal dissipation and SWaP such as ESA elemental signal remoting and processing using power-efficient RF-photonics
  • Research dynamic aperture thinning concepts
  • Research use of RF optics to relax array element spacing.

 

Relevance to the Intelligence Community:

  • Finding novel methods to overcoming challenges of power and thermal management for high density electronics and high frequency ESAs could allow for use on SWaP constrained platforms.
