FM Notch Filter with Low Noise Amplifier LNA 4000MHz; Gain 40+dB

Regular price $54.00


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 LNA module has an integrated FM Notch pre-filter that will reject strong FM signals and allow the receiver to process Airband, AIS, Weather Band and any other signals all the way up to 4 GHz.
The FM Notch Filter is 7th order. The maximum gain of the LNA is greater than 40 dB. That's a lot of gain. If you don't need as much gain, we have a similar product with 20 dB of gain.


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 +5V to +10V 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
