TMD highlighted enhanced S-band transmitter

Article Type: Equipment and software From: Aircraft Engineering and Aerospace Technology: An International Journal, Volume 80, Issue 3.

TMD Technologies highlighted the latest developments to their PTX7602 S-Band Transmitter at the recent ATC Global exhibition. This complete S- band transmitter for commercial or military air traffic control now includes enhanced features and improved user benefits.

TMD's extensive experience in the development and manufacture of high- performance transmitters for aerospace applications, where space is at a premium, has resulted in an extremely compact and modular design.

Unlike previous travelling wave tube (TWT)-based systems, the power supply for the new PTX7602 is built up of a series of separate in-service line replacement units combined within a standard 19in. rack.

The high-voltage sections within each unit are encapsulated in a silicon-based compound, which is said to result in a clean, environmentally friendly oil free transmitter.

At the heart of the transmitter is TMD's PT6055 S band TWT which, combining high efficiency, reliability and long life, has proved an outstanding success in Watchman radars world wide. The PT6055 also offers the advantages of predictable managed power with reliable through life support and reduced total life cycle costs when compared with solid state alternatives.
