100 kHz to 2 GHz LNA
Posted by GPIO Labs on
This is a 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.
What is a Low Noise Amplifier?

A low noise amplifier (LNA) is an electronic device that amplifies weak signals at its input without adding significant noise. These amplifiers are typically used in receivers. For LNAs the most important specifications are:
- Gain
- Noise Figure
- Linearity
