FBKA-29.75G-1 KaBAND FILTER PRELIMINARY REV: 005, 05/19/04 TECHNICAL DESCRIPTION / APPLICATION MULTI-MIX® FILTERS • • • • • • UP TO 40GHz LOW LOSS NO TUNING SMT COMPATIBLE SMALL & LIGHT WEIGHT LOW COST Merrimac’s FBKA Series millimeter-wave filters provide superior performance over conventional filter topologies, with center frequencies as high as 40 GHz. They are extremely small, lightweight, and rugged, and can be qualified for spaceflight applications. In addition, they are low in cost and need no tuning, which makes them an excellent choice for high-volume production in LMDS and other millimeter-wave communications applications. The FBKA Series filters incorporate all of the advantages of Merrimac’s patented Multi-Mix® multilayer fabrication process, including superior electrical characteristics, extremely small size, and negligible part-to-part performance variation. Their benefits include: • Employs fusion bonded stripline with inherent performance benefits at high frequencies. • Passbands as narrow as 1%. • Extremely small size and cost effective. • Can be specified with center frequencies from to 17.5 GHz through 40 GHz. • Designed for wire-bond attachment / BGA compatible. • Tuning is not required, which eliminates the filter-tuning step in production test, along with the external tuning circuits or tuning screws required by conventional designs. • Can be integrated with other Multi-Mix® components in a compact enclosure to form a complete passive or active subsystem. • Inherently low EM emissions. • No spurious reentrant passbands over wide frequency range (up to 65 GHz).
