Precautions when using LNAs
Posted by GPIO Labs on
Our LNA products use a micro-USB connector for powering the device. The choice of this connector was based on the popularity of USB and the reasoning that it's easy to find cell phone chargers. The only negative with this connector is that it is easy to rip them off the board if handled improperly.
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.
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?
Posted by GPIO Labs on
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
