A wideband low-noise amplifier, intended for operation in the 50 MHz – 8 GHz band. The BM series model features a built-in battery providing up to 5 hours of mobile operation, with charging at 210 mA. Thanks to its very high gain (up to 39 dB), it works well as an amplifier compensating for losses in long cable lines – especially when placed directly at the antenna rather than at the receiver.

The module offers high linearity, low noise and stable parameters across a wide frequency range, making it suitable for measurement applications, radio systems and precise RF applications.
