LTE SAW filter for dipole antenna

LTE new filters are designed in accordance with IEC for the attenuation of signals that will be transmitted over the telephone band called 4G (former Banda Television UHF channels E61 .. E69). These filters differ in their selectivity and to the scope of use. They are all made of die, with F connectors or IEC, just to make them suitable to be inserted at any point in the distribution system. The two best performing models, with regard to the steepness of the cut between TV band and Band 4G (LTE), are made with the latest technology, and meet the specifications included in the Guide CEI 100-7 (typical case). A second option is to filter Class A +, made with technology in variable capacitors. This product is used when you have situations of interference LTE rather pronounced. All the others have a less pronounced transition, they are made with an LC type of cells, and find their right use or integration of the models described above, or where the danger of interference was not particularly pronounced.
