Merrimac’s FGBC Series filters allow very wide stopband rejection to be achieved in very small enclosures
without the appearance of reentrant spurious passbands. In addition, they require no tuning once incorpo-
rated in a circuit, making their already economical design even more cost-effective, especially in high-vol-
ume production. The FGBC Series filters incorporate all of the advantages provided by Merrimac’s patented
Multi-Mix
®
multilayer fabrication process, and are an excellent choice for applications in which size and
weight are critical.
