Radar Front Ends (RFEs)

  • X-Band to 100 GHz Capability Range
  • FMCW and Pulsed RFEs
  • Integrated transceivers for production
  • Bolt-together components for Breadboarding
  • Monostatic and Multi-Static configurations
  • Linearized VCO and DDS-based designs
  • 60 GHz Pulsed/FMCW RFE
  • HXI has provided a wide range of Radar Front Ends (RFEs) to various customers for almost 20 years. Starting with a simple 60 GHz hand-held “flashlight” radar for a police department in Japan, HXI established a unique radar capability. Later RFEs included a simple FMCW sensor for railroad crossing safety, which also found use as an in-process monitor in a steel factory. On the more complex side, HXI developed a 94 GHz RFE for helicopter landing in brown-out and adverse weather conditions as well as a 60 GHz pulsed/FMCW RFE breadboard for satellite-based obstacle detection. Examples of Radar Front Ends that we have developed can be found in our Radar Capabilities Brochure.

    HXI more recently has been in development of a Multi-Static FMCW radar designed specifically to detect suicide bomb threats at medium range (50 meters). Breadboard testing has been very successful and a pre-production hardware set is expected to be trialed in late 2013 or early 2014. HXI is a subcontractor on the program and the work is sponsored in part by the Department of Homeland Security. More information on the radar can be found in the download section below - just click on the download for the Model 8300 Radar Front End.

    HXI’s custom-designed FMCW RFE configurations can include either DDS-based or linearized VCO chirping, depending on bandwidth and linearity requirements. Up and downconversion, amplification and other radar transceiver functions in the millimeter wave region are realized largely with MMIC-based circuitry andare custom-engineered for SWaP requirements. RFEs can be breadboarded using HXI’s single function modules, which include LNAs, power amplifiers, mixers and upconverters, frequency multipliers, switches, etc. An example of a 94 GHz RFE breadboard is shown below, along-side the resulting pre-production design that it evolved to.

    HXI partners with various radar developers, signal processing experts and other supporting entities to realize complete radars. On-staff radar knowledge at HXI allows system and hardware tradeoffs to be more easily studied and final configurations decided with a high degree of input to the end customer from HXI.
