Smiths Interconnect|TRAK has over a decade’s experience designing and producing Surface Mount Technology, SMT Isolators and Circulator suitable for pick and place and reflow soldering.
Devices have been produced in a variety of frequencies from L to X-band for applications which include communications, commercial avionics and large AESA programs using Surface Mount Technology (SMT).
Over the years the range has continued to expand to ensure designers have access to the widest choice of robust and reliable products available as single junction Isolators & Circulators or dual junction Duplexers.
Recent product development has focused on improving the breadth of the frequency bands serviced, the electrical performance achievable, and extending the peak power handling. These improvements have been delivered by paying particular attention to ferrite selection and magnetic bias combined with improvements in mechanical packaging that aid and assist the re-flow process including device footprint & interface pre-tinning.
| This table lists the basic information for a range of typical designs. Electrical specification is dependent on several factors including operating bandwidth, temperature and RF peak power. Please contact the factory for performance data. | |||||
