Microstrip Isolators and Circulators

Microstrip isolators and circulators are broadband structures offer a unique blend of broad band operation, low mass & low profile which together make them ideal for use in hybrids for space and terrestrial AESA applications.

Features & Benefits

Smiths Interconnect has a unique heritage having supplied over 400k microstrip isolators and circulators for space and terrestrial based radar and industrial telecommunications applications. TRAK’s capability extends from 2.7 GHz to 31 GHz with unconditionally linear products that include single junction isolators and circulators & dual junction isolators and duplexer.

Key advantages

  • Tuneless broadband structures
  • Lowest mass of any ferrite isolator or circulator
  • Smiths Interconnect devices are made using processes and from materials with outstanding heritage
  • Space qualified and suitable for hybrid applications
  • Exceptional RF performance
  • ITAR free
