1090MHz ACASOM Cavity Filter for ADS-B Systems | Chipomi

The ACASOM 1090MHz cavity filter is designed for ADS-B flight tracking systems, aviation receivers, transponder-related setups, and compatible equipment including Radarcape and FLARM. It operates across the 1086–1094MHz band and helps maintain a cleaner signal path in sensitive RF environments.

With insertion loss up to 0.5dB, the filter keeps signal attenuation low while preserving useful reception performance. High out-of-band rejection up to 75dB helps reduce unwanted interference and supports more stable RF operation.

The unit features a rugged aluminum housing with N-Type connectors. Both RF ports are identical, making installation convenient between antenna and receiver or between antenna and extender.

FAQ:

1. Is this filter suitable for 1090MHz ADS-B systems?
   Yes, it is designed for the 1086–1094MHz working band used in ADS-B applications.
2. Can the filter be connected in either direction?
   Yes, both RF ports are identical, so there is no fixed direction requirement.
3. What equipment is this filter compatible with?
   It is suitable for ADS-B receivers, flight tracking systems, transponder-related setups, Radarcape, and compatible devices.
4. What connector type does it use?
   The filter uses N-Type connectors for RF integration.
5. How much signal loss should I expect?
   Maximum insertion loss is 0.5dB, which helps maintain efficient signal transmission.
6. Can it be installed between the antenna and an extender?
   Yes, the supplier specifically indicates this as a supported connection option.
7. Why is out-of-band rejection important here?
   It helps reduce unwanted signals outside the working range and supports more stable reception.

The ACASOM 1090MHz cavity filter for ADS-B is a practical RF component for users who need cleaner and more stable signal performance in the 1086–1094MHz range. It is built for applications where signal quality matters, including flight tracking systems, aviation monitoring setups, and receiver chains that need controlled filtering. With insertion loss up to 0.5dB, the filter helps maintain useful signal strength while improving the quality of the RF path.

This model is suitable for ADS-B equipment, aviation receivers, Radarcape-compatible systems, FLARM-related setups, and other 1090MHz monitoring projects. Out-of-band rejection up to 75dB helps reduce unwanted nearby signals and supports better reception consistency. That makes it a strong option for installations where surrounding RF activity can affect performance and filtering accuracy becomes more important.

The ACASOM filter comes in a rugged aluminum enclosure with N-Type connectors and a compact 83x55x30mm form factor. Its net weight of 0.4kg makes it easy to integrate into different system layouts without adding unnecessary bulk. Since both RF ports are identical, installation is more convenient whether the unit is placed between antenna and receiver or between antenna and extender.

If you are looking for a 1090MHz cavity filter with low loss, solid rejection performance, and simple RF integration, this ACASOM model is a reliable choice. At Chipomi, you can select filtering components designed for stable signal handling and professional RF system integration.
