Standard Low Pass Filters
RLC Electronics’ Standard Low Pass Filters are available with cut off frequencies ranging from 100MHz to 18 GHz. These filters combine minimum insertion loss and low VSWR in the Pass Band, together with sharp skirt selectivity and high rejection in the Stop Band. This is accomplished by the utilization of multisectional, modern network design. Miniaturization of these units is accomplished by utilizing advanced coaxial techniques and optimum selection of materials. Both lumped constant and distributive techniques are utilized in the fabrication of these filters.
