Improved Low-Power Radio Frequency
See Capabilities


The LPRF is a critical component to the APG-66(V) and (V)2 Fire Control RADAR in the F-16, as well as many other airborne platforms. Due to the age of the LPRF, it is plagued by a low mean time between failure (MTBF) as well as diminishing manufacturing sources and materials shortages (DMSMS). The Improved LPRF (iLPRF) was designed as a form, fit, function replacement to combat these issues. Utilizing the existing qualified chassis, the iLPRF design replaces the obsolete and hard-to-find subassemblies with modern, supportable, and high MTBF components. The iLPRF provides very quick return on investment, and keeps operational availability of the line replaceable unit (LRU) high.

  • Form-Fit-Function retrofit for APG-66 LPRF
  • Mitigates obsolescence by removal of problematic RF SRU’s, but retains some original components to reduce costs and requalification efforts
  • High Mean Time Between Failure
  • Long-Term Sustainable Design
  • Quick Return on Investment
  • No Minimum Quantity Requirements for Upgrade
  • All work performed at Duotech’s facilities and tested in accordance with OEM & USAF standards
  • Reduce repair turnaround time with off-the-shelf components
  • LRU can be reprogrammed to different channels to match Northrop’s original G0X configurations
  • Take old non-repairable LRUs from stock to create new rotatable stock
  • Upgrade non-usable Baseline LPRFs to (V)2 compatible LRPFs
