2.4GHz WiFi Channel 13 Cavity Bandpass Filter 2462–2482MHz ACASOM | Chipomi

The ACASOM 2.4GHz bandpass cavity filter is designed for wireless systems operating in the ISM band. This version is optimized for WiFi Channel 13, covering the 2462–2482MHz frequency range with a 20MHz passband. It is intended for installations where precise signal filtering is required to maintain stable wireless performance.

The filter uses an 8-pole ultra-high-Q cavity design, which delivers strong selectivity and reliable suppression of unwanted frequencies outside the operating band. With an out-of-band rejection level of ≥80dB, the device helps reduce adjacent-channel interference and improves signal stability when multiple wireless devices operate in close proximity.

The housing is built from industrial-grade aluminum, providing mechanical durability and stable RF performance. Nominal insertion loss is approximately 1.5dB, allowing the filter to preserve useful signal strength while improving spectral isolation in RF systems.

This filter features a bi-directional RF design, meaning both ports are electrically identical and can be connected either to the antenna or the access point. The device is intended for indoor installation or integration inside weather-protected enclosures in professional wireless infrastructure.

The ACASOM 2.4GHz WiFi Channel 13 bandpass cavity filter is designed to deliver reliable RF signal filtering in the 2462–2482MHz frequency range. With a 20MHz bandwidth, the device is optimized for WiFi channel operation where precise filtering and stable signal isolation are essential for maintaining consistent wireless performance.

At the core of the design is an 8-pole ultra-high-Q cavity resonator structure, which provides excellent signal selectivity and effective suppression of unwanted frequencies outside the passband. The specified ≥80dB out-of-band rejection helps reduce interference from nearby channels, making the filter particularly useful in environments where multiple wireless transmitters operate in close proximity.

The filter features low insertion loss of approximately 1.5dB, allowing the useful RF signal to pass through with minimal attenuation while still improving spectral isolation. With support for up to 20W of RF power, it can be integrated into a wide range of wireless infrastructure systems, RF engineering setups, and professional communication equipment.

Constructed with a durable aluminum housing and N-Female connectors, the device ensures reliable mechanical and electrical performance. Its compact size of 122x63x26mm makes it easy to integrate into RF assemblies, wireless nodes, and test environments. Available through Chipomi, this ACASOM cavity filter provides a practical solution for improving signal clarity and reducing interference in professional 2.4GHz wireless systems.
