UBBV 1

The Aaronia UBBV 1 is a high-gain preamplifier covering 1 MHz to 1 GHz, designed to deliver maximum sensitivity improvement for RF and EMC measurements in the sub-gigahertz frequency range. With a typical gain of 40 dB and a noise figure of 3.5 dB, it is optimised for boosting weak signals from antennas, probes, or RF sources where sensitivity at lower frequencies is critical.

Key specifications include a maximum RF input of +15 dBm, maximum RF output of +15 dBm, and 50 Ω SMA connectors (female input, male output). It is compatible with any brand of spectrum analyzer and connects directly to Aaronia's SPECTRAN handheld analyzers. Its high compression point of nearly 100 mW also makes it suitable for boosting the output of small RF transmitters.

Each unit is developed, produced, and calibrated in Germany at the Aaronia factory. It ships with an aluminum transport case, international power supply with adapters, SMA tool, and manual. Weight is 146 g with dimensions of 81 × 61 × 29 mm.
