Low-Pass Filters

Main Content

Low-pass filters (LPFs) are designed to pass signals below a certain frequency cut-off point, while rejecting signals above that. CTS low-pass filter solutions come in shape of the Rooftop series (RLF), offering very small size, low insertion loss and significant close-in rejection/attenuation. The RLF product family comes with options for passband and stopband range and is characterized by a shared, universal footprint, allowing any frequency version to be added onto a PCB layout without requiring further modifications.
