Case Studies

Below are just some of the many projects that Lexatys has completed over the years. Lexatys develops unique, compact designs that optimize performance while minimizing package size. Lexatys has capabilities that include miniaturized lumped element filtering, laser-tunable surface mount filters, integrated assembly design up to 40 GHz, and high power, hermetic filter packages. Lexatys has designed and built several integrated assemblies that operate from below 6 GHz up to 50 GHz in range.
