Following initial market adoption and installation Smiths Interconnect is exhibiting its innovative TRAK X-Band Surface Mount (SMT) Circulators at DSEI in London. These units are low-cost, true pick-and-place compatible (tape-and-reel) components with standard solder reflow profiles. They are designed to replace “drop-in” and microstrip style circulators.
They provide a 10% bandwidth at X-Band, a minimum of 20dB isolation, and 0.45dB maximum insertion loss.
These devices offer up to 20W cw of power handling in a 0.25in. square by 0.066in high package, and an operating temperature of -40oC to +85oC.
These circulators also offer high performance with minimal impact on real estate.
They greatly reduce additional costs by eliminating custom mounting configurations required with other circulator styles.
They will easily install onto CCA/PWB exactly as other SMT components. The circulators are optimal for phased array radar antennas as well as EW and Communications systems applications.
Smiths Interconnect is also promising a 30% bandwidth version in a 0.35in square package, and a new S-Band model in a 0.75in square package.
