SDR1 is a low-noise signal amplifier (LNA) designed specifically for the FM band, integrating low-noise amplification, selective filtering and automatic gain control. It effectively enhances weak FM signals while suppressing noise interference, and with its flexible design, can meet the reception optimization needs of various radio devices without changing antennas, making it an ideal accessory for improving signal quality. Widely suitable for various FM band radio devices (such as RTL-SDR, Malachite, HackRF One, SDR6, etc.) to enhance weak signals. It can be used for broadcast coverage extension in signal blind areas such as mountains, tunnels, and underground spaces, as well as optimizing signal quality inside large buildings such as shopping malls, airports, and campuses. It is also suitable for in-vehicle and home broadcast reception optimization, and ensures effective delivery of FM broadcast information in emergency communication scenarios such as disaster relief.
Frequency range: 65 MHz–162.5 MHz (FM band) Gain: up to 30 dB per channel (controlled by on-chip power detector) Noise figure: 3 dB Power supply: 5V 1A
