ADSB Filter Function This passband filter is designed for ADSB interfaces. It passes frequencies from 1 to 1.2 GHz and attenuates signals outside this range to reduce interference. Why you need it If ADSB data at 1090 MHz is degraded by strong outofband signals, this filter helps limit interference and stabilize reception. Key benefits Improves signal integrity for ADSB systems, reduces interference from outside the pass range, and supports cleaner data capture at the ADSB frequency. Specifications Transmission range: 11.2 GHz. Passfilter design to block signals outside the pass range. Compatibility Intended for use with standard ADSB interfaces and receivers. Use scenarios 1) Home or lab ADSB receiver setup in environments with RF noise or nearby transmitters. 2) SDRbased ADSB projects, where filtering improves data quality and decoding reliability. 3) Field testing of ADSB equipment in aviation research or maintenance, to isolate inband signals and evaluate performance.
