Stripline Isolators and Circulators

Our latest SMT designs are the result of more than 30 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 and  naval 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.
