Original Press Release:

X-Band Surface Mount (SMT) Circulator with Low Insertion Loss and Small Package

Tampa, FL – Smiths Microwave Subsystems is pleased to announce the release of the TRAK X-Band Surface Mount (SMT) Circulator. This device is a low-cost, true SMT circulator compatible with tape-and-reel (pick-and-place) and standard solder reflow profiles. It is designed to replace “drop-in” and microstrip style circulators. This unit provides a 10% bandwidth at X-Band, a minimum of 20 dB isolation, and 0.45 dB maximum insertion loss. Offering up to 20 wcw of power handling in a 0.25” square by 0.066” high package, and an operating temperature of -40oC to +85oC, these circulators offer high performance with minimal impact on real estate. They greatly reduce costs by eliminating custom mounting configurations required with other circulator styles and install onto your CCA/PWB exactly the same as other SMT components. These innovative circulators are optimal for phased array Radar antennas as well as EW and Communications systems applications.

Coming soon is an (X-Band) 30% bandwidth version in a 0.35” square package, and a new S-Band device in a 0.75” square package.
