Smiths Interconnect offers a comprehensive range of waveguide, coaxial, stripline, microstrip and SMT of isolators and circulators for a variety of target markets and applications. Frequency of operation starts at around 400MHz (coaxial) and ranges to ~86GHz (waveguide) and all devices are optimised to work in assigned frequency bands. Often there are several potential choices of interface that would provide a suitable solution and understanding the RF power, operating band and any preferred realisation is a normally a good way to start a conversation on what is available. Products are designed, analysed, and optimized for specific applications to operate under worst-case combination of agreed operating conditions found in the intended application.
