PRODUCT OVERVIEW

This is an low noise RF amplifier that provides excellent gain and noise figure. The gain at 100 MHz is 30 dB while the noise figure is 2.2 dB. The LNA can be used in a number of different receiver applications such as Ham Radio, Software radio, TV reception, etc. The product is ideally suited as a pre-amplifier for software radio products such as RTL-SDR, HackRF, USRP, etc., where the USB power supply means you can power it off your laptop.

FEATURES

• Wideband LNA with 30 dB Maximum Gain between 100 kHz and 2 GHz;

• Operational from 100 kHz to 5 GHz

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

• LED power indicator

• SMA-F connectors

• USB powered (cable not included)

• Pads for two-pin power header

The LNA includes a place holder for a Bias Tee inductor. Something that you will have to solder yourself if required. Note that once you enable the Bias tee, you will have to take precautions when powering the LNA over USB as +5V will appear at the RF output. Some receivers cannot tolerate DC.

For best performance mount this LNA close to the antenna to minimize the noise figure.

Here is a video of the LNA being used for shortwave.
