Description
The BBV 9744 B Broadband Preamplifier is a high-performance solution designed for precise EMC and RF measurements where low-level signals need reliable amplification. Covering a broad frequency range of 9 kHz to 8 GHz, this preamplifier ensures accurate results across multiple testing environments. With a typical gain of 29 dB up to 6 GHz and 27 dB from 6 to 8 GHz, it provides the enhanced sensitivity required for capturing weak signals without distortion.
Engineered with a low noise figure of < 2.7 dB @ 1 GHz, the BBV 9744 B maintains signal integrity and reduces background interference, making it highly suitable for pre-compliance EMC testing and antenna-based measurements. Its rugged aluminum enclosure and lightweight design allow for both portable and bench-top applications. The unit features ESD-protected circuitry to safeguard sensitive internal components, while the integrated voltage regulator ensures stable operation even in demanding environments.
To maximize performance, it is recommended to connect the BBV 9744 B directly to the antenna, enabling highly sensitive detection of weak signals. However, it is not advised for broadband impulsive noise measurements due to large-signal limitations.
With its improved input stage protection, extended frequency range up to 8 GHz, and compact build, the BBV 9744 B represents an advanced upgrade for professionals working in EMC testing, RF development, and system verification.
