- Purpose and benefit This FM suppression filter is designed to reduce interference from the FM broadcast band. By attenuating 88-108 MHz, it helps improve signal clarity for other VHF/UHF signals in your receiver or measurement setup. - Attenuation and target band Provides attenuation of about 50 dB or more within the 88-108 MHz range, effectively suppressing the FM broadcast signals that can otherwise bleed into nearby reception paths. - Filter behavior The filter mainly targets the FM band to reduce its influence. It may have limited impact on frequencies outside the 88-108 MHz range, but adjacent bands can be affected depending on system configuration. - Cautions on frequency impact The notch characteristics can affect nearby frequencies, including aviation bands. If aviation frequencies are used in your setup, evaluate the impact before deployment. - Compatibility and integration Suitable for insertion into RF front ends, receivers, and test benches where FM suppression is desired. Exact size and construction depend on the model; please refer to the product datasheet for dimensions and material details. - Key specifications (typical) Band of attenuation: 88-108 MHz Attenuation: approximately 50 dB or more in the target range Outside band effect: minimal but not guaranteed; check with your specific configuration - Use scenarios 1) In a receiver or scanner setup where nearby FM stations cause interference, use the filter to reduce FM leakage and improve reception of other signals. 2) In an RF lab or test bench to suppress FM interference when evaluating equipment on adjacent VHF bands. 3) In broadcast monitoring environments, use the filter to isolate non FM signals, but verify that aviation and other critical bands are not adversely affected.
