Network Sciences was originally founded in 1970 under the name “Network Sciences, Inc.” to design, develop and manufacture discrete crystal filters for the Citizens’ Band (CB) mobile radio and amateur radio industries. In 1985 the current management team acquired and renamed the company “Network Sciences”, and has effectively grown the company’s product line to include a wide variety of discrete crystal filters, LC filters, monolithic crystal filters, and crystal-based frequency discriminators. With over 1,000 proven filter designs in its engineering library, Network Sciences has become known to provide unique solutions to unique applications in the design and manufacture of high quality standard and custom-engineered rf filters covering the frequency range from 1 KHz to over 2.5 GHz.
