Rohde & Schwarz Compact Broadband Amplifier Enables EMC Testing in the Microwave Range

Rohde & Schwarz has introduced a new amplifier family for the microwave range to its EMC portfolio. These compact, lightweight amplifiers with their state-of-the-art design are optimized for high frequencies starting at 0.8 GHz. The first model in the R&S BBA150 family covers the 0.8 GHz to 3 GHz frequency band and is available with an output power ranging from 30 W to 200 W. The R&S BBA150 amplifier family covers a wide range of applications. The amplifiers can be used for EMC testing up to 3 GHz in line with common standards, for instance for EMS measurements in line with the basic EN 61000 4 3 standard and referencing product standards. Manufacturers can also use these amplifiers for non-EMC applications in component production and quality assurance. The amplifiers are suitable for research, physical engineering and communications applications as well.

The compact, modular design of the R&S BBA150 amplifiers enables the flexible setup of complete systems. The 200 W model, for example, requires only four height units – ideal for desktop use or rack installation. These broadband amplifiers feature high availability thanks to their outstanding mismatch tolerance and ability to handle both short-circuiting at the RF end and an open RF output. The result is fewer downtimes and cost savings.

When used in combination with the well-established R&S BBA100, the R&S BBA150 can take advantage of the available RF switching options. If desired, the R&S BBA100 can act as a master to control the R&S BBA150 and integrate it like an additional RF path. The overall system then functions as a multi-band amplifier that optionally has a common RF input, common sample ports and RF switches. Additional, external switching components are unnecessary. Depending on the setup, the R&S BBA150 can be manually operated via its display and buttons or it can automatically controlled via a remote control interface or a web browser.

The R&S BBA150 can be scaled and configured to optimally meet test setup requirements. All of the amplifier’s components are designed as modules. This modular concept protects customer investments and makes it possible to extend the amplifier’s power and frequency range. The worldwide service network is a reliable source of modules and spare parts that promotes the trust and confidence of customers.
