This filter suppresses the broadcast FM band (88-108 MHz) with attenuation of about 50 dB or more. Key benefits - Strong FM suppression: Attenuates 88-108 MHz by approximately 50 dB or more, helping to protect receivers from strong FM signals. - Improves signal integrity in noisy environments: Useful when used with R (RF receivers) in areas where broadcast FM is very strong and can cause overload and poor performance on other bands. - Diagnostic aid for interference: If you observe FM station images or a rise in wideband FM (WFM) interference on other frequencies, this filter can help mitigate those issues. - Caution on adjacent frequencies: The filter’s suppression characteristics are focused on the FM band, but the filter can also affect aviation frequencies due to its frequency response. Product notes - Function: FM band stop filter designed to suppress 88-108 MHz with high attenuation. - Compatibility: Intended for use with R (RF receivers) to reduce FM overload and improve overall frequency performance. - Size and material: Not specified by the manufacturer. - Performance: Attenuation around 50 dB or more in the target band; effects on nearby or aviation frequencies may occur. Use scenarios - Scenario 1: In a location with very strong broadcast FM signals, connect this filter to an RF receiver to reduce FM-related overload and improve reception on non-FM bands. - Scenario 2: In a measurement or test setup, use the filter to suppress FM energy when assessing signals outside the FM band, helping to minimize interference from FM transmissions. - Scenario 3: In a laboratory or field environment where FM leakage could influence WFM measurements, apply the filter to limit FM contamination, while recognizing that aviation frequencies may also be affected.
