Low Noise Amplifier (LNA)

The LNA is used to amplify the NQR signal before it is digitized by the LimeNQR spectrometer.

It needs a 5V power supply and the input and output are marked on the PCB.

The input is usually connected to the Preamplifier Port of the Transcoupler and the output to the RX port of the LimeNQR spectrometer.
