Teseq has expanded its broadband amplifier line to include the CBA 400M-110, a Class A model that operates from 10kHz to 400MHz with a saturated power level of 110W.

The CBA 400M-110 uses gallium-arsenide (GaAs) integrated circuit technology, which is claimed to provide better compression characteristics and efficiency than comparable silicon-based power amplifiers.

This power amplifier is designed for demanding EMC testing environments with non-ideal load conditions due to mismatch caused by the coupling device or equipment under test (EUT) in the antenna’s path, making it suitable for automotive, military and aerospace BCI EMC testing.

According to Teseq, the GaAs amplifier circuit’s Class A push-pull design ensures linear performance with high reliability and low distortion, as well as continued operation at full power, even when an open or short circuit is present.

Key benefits

  • Harmonics better than -20dBc at 80W output
  • Low distortion across the 10kHz to 400MHz operating range
  • Integrated front-panel indicators reveal over-temperature and RF interlock conditions
  • Integral fans ensure it is kept cool
  • Powered from a switched-mode power supply
  • Remote-control option available
  • Operating temperature range: 0-40°C (32-104°F)

Teseq — EMC test solutions: combining tradition and experience with dynamic and innovative development 

Teseq is the new name of the Test Systems Division that belonged to the Swiss-based Schaffner Group until it became an independent company after a management buyout in 2006.  

Teseq has retained all of the former Schaffner Division’s management and employees ensuring business continuity, commitment to existing and new customers and a dynamic approach to new product development.  

Teseq also continues to stand for customised client support, proven products and extensive know-how. The company’s focus on its core business — EMC test solutions — will be reinforced by greater attention to innovation in the area of research and development. The streamlined size of the enterprise ensures maximum independence, agility and flexibility.  

Teseq offers standalone products and complete solutions for EMC conducted immunity testing including: ESD generators; harmonics; flicker and power quality test systems. It also provides a complete range of EMC radio frequency test equipment from measuring receivers, power amplifiers and GTEM cells to very powerful software for the automation of EMC test houses.    

Teseq’s extensive knowledge of EMC systems can be found in more than 90 countries worldwide with hundreds of systems installed in applications such as automotive, military, telecoms, commercial and medical.
