Filtr 1090 MHz

1090MHz bandpass RF filter is professionally optimized for ADS-B (Automatic Dependent Surveillance-Broadcast) aviation reception. It passes 1090MHz aircraft transponder signals while blocking strong interference from nearby frequency bands, greatly raising receiver dynamic range and reducing false signals for flight radar & aircraft tracking projects.

It features ultra-low insertion loss and excellent stopband attenuation. 50Ω impedance with SMA/N interface, indoor and outdoor options are available, easy to connect to SDR radio, ADS-B antenna and receiver. Compact and lightweight design for both fixed ground station and portable flight tracker setup.
