Description
Microsemi’s Miniature Ferrite Isolators are H-Plane, Y-
Junction devices with similar performance
specifications to standard size isolators. Models are
available in bands covering center frequencies from
18–110 GHz and feature low insertion loss and high
isolation within the specified bandwidth.
MMI series isolators are useful in improving the
stability of microwave oscillators and amplifiers by
projecting matched impedance across the frequency and
preventing reverse and reflected power from adversely
affecting performance.
