an ultra-low-power low-noise RF amplifier, operating in the 100 kHz to 4 GHz range. The BM version is equipped with a built-in battery, making it ideal for portable applications. The internal rechargeable battery provides up to 20 hours of operation, and charging is performed at 210 mA. The module is designed for applications requiring high sensitivity and low noise, such as spectrum analyzer front ends, antenna systems, and RF receivers.

Thanks to the built-in bias circuit and low power consumption, it performs excellently in mobile environments, offering stable gain and high overload resistance. It can be used as a replacement for popular amplifiers such as SPF5189Z and SPF5043Z.
