About Us

ComNav Engineering was established in 1991 and incorporated in the state of Maine in 1994 by Martin J. Geesaman. Initially the company operated as a sole proprietorship providing engineering consulting services to several microwave filter companies. During this period, a software program entitled Filtroid was developed to assist engineers in designing microwave filters.

ComNav Engineering, as a manufacturer, began as a product group of Control Devices, a GTE subsidiary. Martin Geesaman and Scott Burgess spent three years doing research and development of various coating techniques and ceramic filter typologies. The result was a superior coating technique that yields unparalleled unloaded Q and adhesion. This coating technique along with several proprietary filter typologies translate into the low loss high performance filter structures that are the corner stone of ComNav's product line today.
