Stripline Isolators & Circulators
Smiths Interconnect|TRAK has produced stripline isolators and circulators devices for over 40 years. The range of available designs continues to expand with a number of applications for terrestrial and space based products seeing renewed interest.
Drop-in devices are available from a huge number of potential suppliers. When customers select Smiths Interconnect|TRAK it is normally the result of a complex combination of factors including the broadest choice of operating frequency, unrivalled quality and industry leading service.
Our latest SMT designs are the result of more than 10 years experience in the design and qualification of similar devices and based on having supplied over 50,000 ferrite junction for AESA applications for land applications.
The use of Stripline ferrite isolators has increased over the years and the trends towards ever higher operating power, frequency and the desire for lower cost integration is relentless. This has resulted in Smiths Interconnect|TRAK supplying more drop-ins for space applications in the past 2 years than it has in the preceding 10 years as renewed interest in LEO & MEO S-band communication and GNSS services has driven increased demand.
Traditional tabbed drop-ins are available in most bands from 300 MHz to 20 GHz and in certain radar bands as true SMD devices suitable for pick and place and solder reflow.
