ADS B Filter Function and range Transmission range: 1 1.2 GHz Purpose: used to modify ADS B interfaces with a pass filter that allows frequencies within the range to pass while preventing interference from signals outside this range Interference scenario: if you experience major interference from out of band signals around 1090 MHz, this filter may be useful for ADS B installations Key benefits Improves signal integrity by blocking unwanted frequencies outside the 1 1.2 GHz pass band Simple integration with existing ADS B interfaces to reduce RF noise Helps protect ADS B reception from out of band interference while preserving the desired 1090 MHz signal Compatibility and attributes Compatibility: designed for ADS B interfaces and systems Size: not specified Material: not specified Performance: pass band 1 1.2 GHz with out of band attenuation as described Use scenarios Home ADS B ground station in areas with RF clutter near 1090 MHz, to improve clarity of received data Field testing of ADS B transceivers to ensure clean input signals by filtering stray frequencies outside the 1 1.2 GHz range Portable or vehicle installed ADS B setups where reducing external RF interference helps maintain reliable reception during travel or outdoor operations
