Designed as single-band solutions, these units cover the entire frequency range from 1 GHz to 6 GHz without band switching, significantly increasing efficiency in automated test sequences.
Requirements in the automotive, aerospace, and defense sectors are constantly increasing. The precise generation of high field strengths is essential, especially for vehicle component testing, complete vehicle testing, and high-intensity radiated field (HIRF) applications. The BBA300 family utilizes advanced solid-state power amplifier (SSPA) technology, offering greater availability and robustness compared to traditional traveling-wave tube (TWT) amplifiers.
The units are designed for a wide range of modulation types, from standard amplitude and pulse modulation to complex OFDM signals. Thanks to their high linearity and extreme tolerance to mismatch, these amplifiers deliver reproducible measurement results even under demanding load conditions.
A key feature of the new high-power classes is their high power density. The systems are housed in 30U racks pre-configured for horn antenna mounting. To minimize signal loss at high frequencies, the RF output (optimized with 7/16 connector characteristics) is located in the center of the rack. This shortens the path to the antenna and optimizes the system's link budget.
The BBA-PK1 option (available for the BBA300-DE500) allows the unit to be flexibly adapted to specific test requirements. Users can adjust the polarization point to prioritize either maximum linearity for complex signals or accurate reproduction of pulsed signals. Furthermore, the ratio between output power and mismatch tolerance can be individually configured.
“By expanding the BBA300 series to 1000 W in single-band operation, we are directly responding to our customers’ needs for faster testing speeds and greater system reliability,” says Ralf Heinrich, Product Manager at Rohde & Schwarz. “The combination of solid-state robustness and the ability to operate at ultra-wideband frequencies without band switching sets a new standard for efficiency in electromagnetic compatibility (EMC) testing facilities.”.
The BBA300 family features a modular design. Existing systems can be expanded or combined with other amplifier families, such as the BBA130/150, to create customized system solutions. This ensures a high level of investment security for test centers and development laboratories.
