FM Notch Filter with Low Noise Amplifier; Gain 20 dB and Operation to 3 GHz

Regular price $42.00


This is a Pre-Filtered Low Noise Amplifier.

Very often signals in the FM band can saturate your receiver and kill the benefit of a Low Noise Amplifier. This module has an integrated FM Notch Pre-filter that will reject strong FM signals and the LNA will amplify Airband, AIS, Weather Band and any other signals all the way up to 3 GHz.

The FM Notch Filter is 7th order. The maximum gain of the LNA is 22 dB.



The module can be powered using any one of three different methods:
1.  USB with the use of a Micro USB cable 
2.  DC header - a wide input voltage range of +4V to +12V DC can be used. Please note that there is no reverse-polarity protection on this device so careful with the + and - terminals
3.  Bias Tee - you can solder an inductor onto the provided 0805 footprint and provide DC over the RF output cable
