The LNA125 is a low noise amplifier that employs the PGA-103+ from Minicircuits. It is designed to operate in the VHF band starting from 125MHz to 160MHz. The LNA125 amplifier covers the air band, weather satellite LRPT band and the 2-meter amateur radio band. It provides excellent noise figure performance and very good linearity while strongly rejecting the overpowering FM broadcast band. This amplifier can be powered via the coaxial line or through two pin headers, providing flexibility in power options. It operates with a voltage range of 5V to 12V and draws minimal current to operate efficiently. The open design of the LNA125 allows for easy modification and component replacement, enabling users to enhance the performance even further by upgrading individual parts.

The 3.1mm diameter mounting holes allow the user to firmly screw the circuit board to a sturdy mounting frame, box or a chasis. Additionally, you can also use these holes to assemble appropriate PCB spacers to prevent the bottom of the board from touching anywhere.

The LNA works directly with the RTL-SDR bias-tee and demonstrates superior signal quality. It provides low noise figure, strong FM band rejection and enhances airband, EME, LRPT and 2m band reception. Oh, not to mention crisp SSTV images from the ISS!
