The X-Band Surface Mount (SMT) Circulator from TRAK Microwave is a low-cost, true SMT circulator compatible with tape-and-reel (pick-and-place) and standard solder reflow profiles. It has been designed to replace “drop-in” and microstrip style circulators. The Circulator provides a 10% bandwidth at X-Band frequencies with a minimum isolation of 20 dB, insertion loss under 0.45 dB and can handle up to 20 Watts of CW power.
This circulator is available in a 0.25” square by 0.066” high package, and can operate in at a temperature range from -40 C to +85 C. The circulator offers high performance with minimal impact on real estate. It reduces costs significantly by eliminating the custom mounting configurations required with other circulator styles and installs onto your CCA/PWB exactly the same as other SMT components. The circulator is optimal for phased array Radar antennas as well as EW and Communications systems applications.
TRAK will soon release an (X-Band) 30% bandwidth version in a 0.35” square package, and a new S-Band device in a 0.75” square package.
