Filter Line

Merrimac's filters are manufactured using our patented Multi-Mix® multilayer fabrication process. This allows us to manufacture these parts in high quantities at lower costs. We use fusion-bonded stripline, which provides us with performance benefits at high frequencies. Passbands can be as narrow as 1%. The filters do not need to be tuned, which eliminates the filter-tuning step in production test, along with the external tuning circuits or tuning screws required by conventional designs.

Narrowband ROC Filter

The FBGW Series are bandpass filters with unique properties that make them extremely well suited for applications in which extremely narrow bandwidths, small size, low insertion loss, moderate power levels, and easy intergration with other components, are critical. The FBGW Series represents the first commercial production of filters that combine extremely narrow bandwiths with exceptionally small size in a planar, multilayer structure.

Combline ROC Filter

Merrimac's FBGC Series combline 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 incoporated in a ciruit, making their already economical design even more cost-effective, especially in high-volume production. The FBGC 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.

Interdigital ROC Filter

Merrimac's FBGI-7.6GHz Series interdigital bandpass filters combline 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 typically offer better overall performance than interdigital filters designed to the same specification with conventional filter fabrication techniques.

5-Channel Multiplexer Filter

Merrimac's FBG Series hairpin resonator bandpass filters are designed in Merrimac's patented Multi-Mix® planar, multilayer fabrication process. As a result, they have unique characteristics that make them well suited for applications in which size, weight, and cost are critical parameters.

KA-Band Filter

Merrimac's FBKA Series millimeter-wave filters provide superior performance over conventional filter topologies, with center frequencies as high as 40 GHz. They are exptremely 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.
