The Amplifier Research LN1000BM3 is a low-noise preamplifier module engineered for sensitive receiver applications and laboratory signal conditioning across a broad frequency spectrum. Operating from 10 kHz to 1000 MHz, the unit delivers 30 dB minimum gain with ±1.5 dB flatness, making it ideal for amplifying weak signals ahead of power amplifiers or improving receiver sensitivity. Noise figure of 3.5 dB typical (4.5 dB maximum, 2–1000 MHz) and +21 dBm IP3 ensure minimal signal degradation in demanding measurement environments.
