API Technologies’ reputation for designing and delivering some of today’s most challenging Bandpass filters is the reason why engineers trust us with their designs. Choosing from a wide assortment of topologies, including lumped element, cavity, ceramic, SAW, tubular, suspended substrate, and waveguide; our engineers match the optimum topology to your requirements.

Unlike one dimensional filter companies, SMI continues to prove that by offering multiple options, a customer can weigh the benefits of: size vs. loss, rejection vs. size, selectivity vs. group delay...and select the best filter to optimize system performance.
