About The Technology


Ceramic Fixed Band Reject Filters

Dielectric resonator filters are available as an open frame or packaged product, supporting narrow bandwidths and low insertion loss. Packaged RF Ceramic Filters can be sealed to gross or fine leak specifications and are available in connectorized form or with gull-wing or flat pack hermetic pins for input and output connections. KEL-fil products are open frame, surface mount Ceramic Filters, designed for applications requiring superior temperature stability and high Q response. The entire line of Ceramic Filters is extremely temperature stable and comes at a lower cost point than other available filters, adding to the overall value of the product.
