Description
M/A-COM’s surface mount circulators and isolators, designed for
cellular applications, feature high performance at low cost. These
designs offer the best isolation per insertion loss ratio in the
industry and are currently produced in the tens of thousands of
pieces per year. These units can be ordered so as to be compatible
with solder reflow manufacturing techniques. Both circulators and
isolators are in stock at all authorized M/A-COM distributors.
