What We Do

Relocatable Jammer (RLJ)

The ability to test and evaluate our systems against realistic threats is a
critical step in the development of the DoD’s Electronic Warfare and Sensor
development process. Yet it is often difficult to schedule the ranges, labs or the
equipment necessary for adequate testing or verification. To help resolve this
problem, MacB worked with the Air Force Research Laboratory (AFRL) to design, develop, build and deploy the Re-Locatable Jammer (RLJ) system using a Field Programmable Gate Array (FPGA) based Digital Radio Frequency Memory (DRFM) and advanced Digital Signal Processing technology. Several RLJ units now exist that can be deployed virtually anywhere, from laboratories to open air ranges, to facilitate testing efforts. The units are built by MacB and owned by AFRL.

Relocatable Jammer

Main Characteristics of the RLJ Units:

  • Developed for the U.S. Air Force Research Laboratory (AFRL)
  • Field-deployable, FPGA-based coherent radar jammer and target generator
  • Emulates foreign threats to assess U.S. EW capabilities
  • Designed by MacB to meet unique customer testing requirements
  • Units are Government-owned, MacB-built
  • Continually upgraded through several generations

Digital Radio Frequency Memory (DFRM) features:

  • Two – 1GHz 1-bit Digital-to-Analog Converters (DAC)
  • Four – 62.5MHz Analog-to-Digital Converters (ADC)
  • USB port for host / Graphical User Input (GUI) interface
