LaNA HF Barebones – Ultra Low-Noise LF, MF & HF Amplifier (LNA) Module for RF & Software Defined Radio (SDR). Wideband 50kHz-150MHz Frequency Capability with Bias Tee & USB Power Options

FOR FULL SPECIFICATIONS AND DETAILS, PLEASE REVIEW THE PRODUCT PAGE AT NOOELEC
LaNA HF Barebones is a very high performance, wideband and linear LNA module designed for SDR applications in the HF band and adjacent bands. Power consumption is less than 30mA.
LaNA HF Barebones greatly improves performance when used with Ham It Up upconverters, direct sampling SDRs, and most HF-capable radios and rigs!
Each module allows for 3 different power options, but you should only power with one option at any given time! The recommended power input through the SMA output port (for bias-tee capable SDRs like the NESDR SMArTee) is 4.5V-5V DC. Alternatively, if you don’t have a bias-tee capable SDR, you can use the external power options–the microUSB port, or the power input header. The recommended external power input is 4.0V-5.5V DC.
Though there is protection circuitry on LaNA HF Barebones for overvoltage conditions–and voltages of up to 12V DC should still work and will not damage the device–it is not recommended for long-term usage. Kindly note that damage resulting from overvoltage conditions would not be covered under the standard warranty.
Each LaNA HF Barbones module has an EMI shield to protect the sensitive circuitry from external interference and is fully ESD-protected. LaNA HF Barebones also has an RF limiter at the input port to protect the amplifier from very high power external signals.
