VISAT's 3D vertically integrated RF front end architecture.




During the last ten years, EMAG Technologies Inc. has arduously pursued the development of a "generic" RF front end architecture that can be scaled over different frequency bands. The goal is to realize a modem-agnostic architecture the can be readily scaled, reconfigured and "programmed" to meet different power requirements, and at the same time, provide a versatile beam steering capability. In pursuit of that goal, EMAG Technologies Inc. has developed a patented antenna technology dubbed VISAT™ (Vertically Integrated Scalable Array Tile).

VISAT utilizes a compact, three-dimensional, vertically integrated architecture for active electronically scanned antenna (AESA) systems based on low-cost printed circuit board (PCB) manufacturing processes. A VISAT tile is a complete self-contained RF front end with DC, IF and digital control (SPI) connectors. The extremely low-profile stack contains all the amplification, frequency conversion and beam control stages. VISAT tiles can be tiled together and create larger apertures for higher aperture gains. A VISAT tile has a built-in thermal management system and can provide unmatched levels of SWaP (size, weight and power). EMAG offers VISAT solutions for a wide frequency range from L band (~1GHz) to Ka band (~40GHz).

The VISAT architecture allows several different types of functions to be integrated into a single aperture. A shared multifunction aperture provides numerous system integration opportunities such as combining a communications front end with a precision tracking system to address the beam pointing challenges of directional data links. A few examples of VISAT applications include:

  • Secure or covert directional communication systems
  • Tactical data links in networked battlefield environments
  • Satellite communications on-the-move
  • Cooperative asset tracking
  • Projectile guidance systems
  • Collision avoidance radar systems

EMAG Technologies Inc. has developed a wide range of communications, radar and tracking solutions based on the VISAT technology. Our scalable RF front end solutions are modem-agnostic and can easily be integrated and interfaced with your software-defined IF or baseband back ends. It is as simple as a few connectors: DC, IF, and digital control lines. The VISAT technology can give you a significant competitive edge from a cost-performance standpoint. Due to the proprietary nature of the technologies involved, we encourage you to contact us and discuss your specific requirements for further exploration of possible opportunities.
