Isolators and Circulators

For K, L and X-Bands

High power devices feature composite adiabatic technology designed for optimum thermal handling without compromising the careful electro/magnetic balance required to achieve leading performance while optimum isolation performance and reverse power handling is achieved by using a suite of high power resistive elements which utilize film technologies. All designs are vented with the position of the vents optimized as a result of careful analysis and design proving tests.

Information about Restricted MaterialsRestricted Materials compliance logo

To find out if part number(s) meet regulatory substance or materials compliance (e.g., REACH, RoHS, or any other regulatory requirement). Contact us for compliance verification.

Features & Benefits

  • Most radar and communication bands are included in a portfolio of low power devices
  • Configured as Isolator (2W standard termination) or Circulator
    • For other termination ratings contact the factory
    • Termination resistance is 50Ohm unless otherwise agreed
  • Broad range of X-band passive components for space and defence applications
  • Isolators contain BeO terminations and Sn62/63 is used in the manufacturing process. REACH statements can be provided upon request
