Description
Microsemi’s Miniature Ferrite Isolators are H-Plane, YJunction
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.

MMI isolator part numbers are designated by indicating
the center frequency and waveguide size and flange type.
For example, the MMI22599T at 33.5 GHz indicates
WR22 waveguide, UG599/U-M flange with threaded
holes at 33.5 GHz center frequency. For a through-hole
flange the part number is MMI22599.
