A Heritage in Microwave Components
The original crew, 1936
Our roots in precision machining and sheet metal fabrication expanded into Cellular filters in 1980, when Bell Laboratories the R & D division of ATT involved us in the manufacturing of new products for the then infant mobile phone market. By 1990 we become one of the prime suppliers to Lucent Technologies a descendent of the ATT breakup. Then in 1995 Bartley RF Systems was formed supplying filters and filter panels to the wireless base station market. The division was sold 2001 and is now a division of Andrew Corporation.
The ULTRA-Q FilterIn 2002 while working with AeroComm Inc. of Englewood Cliffs, NJ we learned of the ULTRA-Q filter and it's unique capabilities. When in 2003 when AeroCom ceased operations we secured the patent, inventory and technology. Today, ULTRA-Q filters are deployed in communication systems throughout the country, including tunnels, airports, in-building, land mobile radio systems and public service emergency radios as well as SCADA systems.
