FILTERS
Merrimac’s FBGI Series bandpass filters combine the features of Merrimac’s
patented Multi-Mix® multilayer fabrication technology with the ability to operate to
three times their center frequency without reentrant spurious passbands. They typi-
cally offer better overall performance than filters designed to the same specification
with conventional filter fabrication techniques.
