Cavity Filters

Cavity Filters

Cavity filter designs are available in the frequency range of 30 MHz to 40 GHz and with bandwidth options from less than 0.5% to over 66%. Cavity filters offer the user very low insertion loss, steep skirt selectivity, and narrower bandwidths than discrete component filters.

Ceramic Filters

Ceramic Filters

Ceramic Filters are manufactured in two basic styles for both commercial and military 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 find wide usages in military applications. 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.

Discrete Filters

Discrete Filters

Miniature discrete component filters are designed to give optimal performance where small size is critical. Electrical and mechanical requirements for each design are computer-generated, taking into consideration realizable "Q" and environmental conditions, then analyzed using our unique software, thereby reducing the amount of trial and error alignment.
