2.4GHz 80MHz WiFi Bandpass Cavity Filter 2400–2483.5MHz 8-Pole ACASOM | Chipomi

The ACASOM 2.4GHz bandpass cavity filter is designed for RF systems operating in the ISM band and WiFi infrastructure. This model supports the full 2400–2483.5MHz frequency range with an 80MHz bandwidth, allowing reliable filtering across the entire 2.4GHz WiFi spectrum.

The device is built using an 8-pole ultra-high-Q cavity resonator design, which provides stable signal selectivity and effective suppression of unwanted frequencies outside the operating band. With ≥60dB out-of-band rejection, the filter helps reduce external interference and improves signal stability in wireless environments where multiple devices operate nearby.

Its industrial aluminum housing ensures mechanical durability and consistent RF performance. The filter also features low insertion loss of approximately 1.0dB, which allows the useful RF signal to pass with minimal attenuation while still improving spectral isolation.

The filter uses a bi-directional RF architecture, meaning both ports are electrically identical and can be connected either to an antenna or to an access point. It is designed for indoor installation or integration inside weather-protected enclosures used in professional wireless equipment.

The ACASOM 2.4GHz 80MHz bandpass cavity filter is engineered for wireless systems operating across the full 2400–2483.5MHz ISM band. This frequency coverage allows the filter to support WiFi infrastructure and RF systems that require stable filtering across the entire 2.4GHz spectrum. By maintaining a consistent passband, the filter helps maintain signal quality while minimizing unwanted interference.

The device uses an 8-pole ultra-high-Q cavity resonator design, which improves signal selectivity and allows effective suppression of frequencies outside the operating band. With an out-of-band rejection level of ≥60dB, the filter can reduce the impact of nearby RF sources and help stabilize wireless communication performance.

Another advantage is its low insertion loss of approximately 1.0dB, allowing RF signals to pass through the filter with minimal attenuation. The device supports up to 20W of RF power, making it suitable for integration into wireless infrastructure nodes, RF engineering systems, and professional communication equipment.

The filter features SMA-Female connectors and a durable aluminum housing with compact dimensions of 75x45x29mm, allowing convenient integration into RF assemblies. Available through Chipomi, this ACASOM cavity filter provides a practical solution for improving signal clarity and reducing interference in professional 2.4GHz wireless environments.
