The MFB-1445SM is a passive MMIC bandpass filter. It is an integrated filter that passes Ku-Band frequencies (13.6-15.1 GHz). Passive GaAs MMIC technology allows production of smaller filter constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances allow for less unit to unit variation than traditional filter technologies. Low unit to unit variation allows for accurate simulations using the provided S2P file taken from measured production units. The MFB-1445SM is available as a 3 X 3 mm QFN package. Evaluation boards are also available.


The electrical specifications apply at TA=+25°C in a 50Ω system.[1][2]

Min and Max limits are guaranteed at TA=+25°C.

[1] Filter is symmetrical. Reverse measurement is equivalent to forward measurement.

[2] All measured data is taken from the eval board without de-embedding of the connectors and traces.
