Rohde & Schwarz has added the R&S BBA150 for the microwave range to its EMC portfolio. These compact, lightweight amplifiers are optimised 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 to 200 W.

The 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 BBA150 amplifiers enables the flexible set-up of complete systems. The 200 W model, for example, requires only four height units - suitable for desktop use or rack installation. These broadband amplifiers feature high availability thanks to their mismatch tolerance and ability to handle both short-circuiting at the RF end and an open RF output.

When used in combination with the BBA100, the BBA150 can take advantage of the available RF switching options. If desired, the BBA100 can act as a master to control the BBA150 and integrate it like an additional RF path. The overall system then functions as a multiband amplifier that optionally has a common RF input, common sample ports and RF switches. Additional, external switching components are unnecessary.

Depending on the set-up, the BBA150 can be manually operated via its display and buttons or it can be automatically controlled via a remote control interface or a web browser.

The BBA150 can be scaled and configured to meet test set-up 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.
