X-Band surface mount circulator with low insertion loss and small package from TRAK

Smiths Microwave Subsystems announced 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.
