Smiths Interconnect|Lorch’s Ceramic Filters are manufactured in two basic styles for commercial applications. The high volume, low cost units in open frame, non-hermetic packages are most often used in commercial applications. The lower volume, custom designed hermetic packages. Both styles are available in various mounting configurations. In both instances the same high “Q” coaxial resonators are used which yield low insertion loss and excellent stability over temperature. A low ripple Chebyshev transfer function is standard with bandpass filters and diplxers available.
