Low Noise Amplifier 10 MHz to 8000 MHz with 40 dB gain

Posted by GPIO Labs on



This is a wideband low noise amplifier that provides excellent gain (35-40 dB between 100 MHz and 2 GHz) and noise figure (3 dB at 2 GHz). The LNA is very general purpose and can be used in a number of different applications such as Ham Radio, Software radio, TV reception, etc. The product is ideally suited for software radio products such as RTL-SDR, HackRF, USRP, etc. where the USB power supply means you can power it off your laptop. Our design is unique as it provides broadband performance from 10 MHz to 8 GHz at a fraction of the cost of similar LNAs. As well, all our products are made with genuine ICs sourced directly from the manufacturer and reliable distributors.


• Wideband LNA operates from 10 MHz to 8 GHz

• USB-powered; includes pads for external DC power

• Suitable for use with software radio receivers such as HackRF, RTL-SDR, USRP, etc.

• 2.9 dB Noise Figure at 2 GHz

• PCB edge-mount connectors are SMA-F

• Micro USB cable not included
