0.1MHz To 6GHz Ultra Low Noise RF Preamplifier 20dB Gain

Meet the 0.1MHz to 6GHz Ultra Low Noise RF Preamplifier with 20dB gain from MOJOYCE. This high-performance LNA is engineered for ultra-low noise amplification and superb linearity across a wide band, making it ideal for SDR enthusiasts, field communications, and sensitive RF reception. With a noise figure as low as 0.4 dB at 1.95 GHz and a 20 dB gain at the same frequency, you’ll experience clearer signals, improved reception sensitivity, and reduced degradation in challenging environments. The module uses a 50 ohm interface with an SMA female connector, and its compact size (45 × 45 × 18.5 mm) and light weight (46 g) make it easy to integrate into compact setups. It operates from a 5V supply at 70 mA and can be paired with an optional 3.7V 200 mAh battery for portable use. Originating in Mainland China, this ultra low-noise gain block delivers reliable performance across the full 100 kHz to 6 GHz band.

Benefits & Tips

• Clearer reception: Place the LNA close to the antenna to maximize signal gain and minimize noise pickup in wideband RF systems.
• High linearity: Enjoy strong signal environments with low distortion thanks to a +35 dBm output IP3, even when nearby signals are strong.
• Portable option: For field use, consider the optional 3.7V 200 mAh battery to enable handheld operation without a dedicated power supply.
