LTE filters and Preamplifiers - N.E.L. SRL

LTE 5G filters are created to significantly reduce disturbances linked to the transmission of signals by telephone broadcasters. Significant attenuation is guaranteed, at least 45dB, in the frequency range between 738 MHz and 821 MHz.

 

Preamplifiers were created with a dual function: amplifying the incoming signal and reducing disturbances linked to the transmission of signals by telephone broadcasters. A certainly relevant fact is the very low noise figure that characterizes them: > 2dB. At the same time, generous attenuation is guaranteed, at least 35dB, between 738 and 821 MHz. The two models are distinguished by the type of use, one dedicated to applications inside the home, with a quick male F connector to be inserted into the input connector of the amplifier and female F connector, connected to the cable coming from the antenna. The mast version is characterized by two female F connectors and is covered in an ABS chassis with internal gasket; its fixing to the pole must be carried out using the professional clamp supplied.
