FBGC-2.75G FILTER PRELIMINARY REV: 002, 05/07/04 TECHNICAL DESCRIPTION / APPLICATION MULTI-MIX® FILTERS • UP TO 40 GHz • LOW LOSS • NO TUNING • GPS • SURFACE MOUNT • TAPE & REEL • LOW COST 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 incorporated in a circuit, making their already economical design even more cost-effective, especially in high-volume 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.
