A.T. Wall to Feature Waveguide Tubing

September 23, 2009

A.T. Wall Co., a supplier of precision tubing and fabricated metal components, will feature a range of precision-drawn, high-quality waveguide tubing at the 39th European Microwave Conference (EuMC), September 29th - October 1st, in Booth 703B. Highlighted products will include Invar waveguide, thin wall aluminum waveguide and seamless flexible waveguide. A.T Wall’s broad selection of waveguide tubing is available in-stock, allowing for fast and efficient turnaround time to meet the special product requirements of customers.

Invar waveguide features unique low expansion characteristics allowing minimal expansion in extreme cold and heat. It has the lowest coefficient of thermal expansion of all metals in the –273 to 177°C range. Microwave filters made from Invar can withstand extreme temperature shifts while maintaining the physical characteristics that control the RF signal.

Thin wall aluminum waveguide and seamless flexible waveguide are applicable to airborne systems and space in all satellite applications. Systems designed with aluminum tubes with ½ of or less of the standard wall thickness and performance of heavier walled products allow engineers to save thousands of dollars in a launch. Flexible waveguide also saves the customer money by reducing space needs with its ability to be bent to fit into small spaces.

A.T. Wall will also feature sidewall frames for hybrid microelectronic circuit packages used in defense, commercial electronics and medical applications worldwide. These tubular frames serve as sidewalls for hermetically sealed flat packs that demand restrictive dimensional tolerance and precise metallurgical qualities.
