M/A-COM's drop-in 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.
