This FAQ pertains to LaNA, Nooelec's own wideband low noise amplifier. If you are looking for information on a difference device or product series, look for the appropriate FAQ on the left!
See our comprehensive datasheet for this product here.
What is LaNA?
LaNA is a high-performance wideband LNA module designed for general purpose SDR applications.
What type of applications can I use LaNA for?
+20MHz applications that require an extra RF gain while making sure that the input power is less than 0dBm (1mWatt).
How much gain can I expect to receive with LaNA?
The gain (amplification) is dependent on the frequency you are trying to receive. Based on our own testing of the device, the expected gain throughout the frequency band is:
|Frequency (MHz)||Gain (dB)|
What is the noise figure?
The noise figure (NF) is dependent on the frequency you are trying to receive. A breakdown of expected noise figures by frequency is included in the product data sheet (linked below).
How much power is required to operate LaNA?
Power consumption ranges from about 50-80mA, depending on the input voltage. There are 3 power input options, including: DC power through a bias-tee capable SDR, the micro USB port, or DC barrel connector.
I’m powering my LaNA externally via the USB port, but it doesn’t work when connected to my SDR. What’s happening?
It is important to note that some SDRs would have their ESD protection diode tripped by LaNA when powered externally. You can still use the LNA with these SDRs of course, but you would need to install a DC block between the LaNA and SDR. This can be as simple as a low-distortion, high-quality capacitor in series with the RF path, should you prefer a DIY solution.
