BPF24-401

Overview

The L-com BPF24-401 is a HyperLink 2.4GHz, 4-pole ultra-high Q Wi-Fi channel filter designed for indoor signal conditioning. It operates with a center frequency of 2412 MHz and a bandwidth of 30 MHz, covering the 2397 to 2427 MHz range. The device features an insertion loss of 2 dB and utilizes N-Type connectors in an in-line module configuration. Constructed from rugged aluminum, it provides lightning protection via DC short and is intended for co-located equipment installations to reduce out-of-band interference.

Feature Summary

• Ultra-high Q 4-pole design for precise channel filtering
• Rugged aluminum construction for durability
• Integrated lightning protection through DC short mechanism

Applications

• Co-located Wi-Fi equipment installations
• Indoor RF signal conditioning
• Interference reduction in WLAN environments

Procurement Notes

Verify that the specific application requires the Channel 1 designation (2412 MHz center frequency) rather than other channels within the 2.4 GHz band. Confirm compatibility with existing N-Type connector interfaces on both input and output paths. Ensure the indoor rating aligns with the installation environment, as this model is not specified for outdoor exposure without additional weatherproofing measures.

Selection Notes

Select this component when a single-channel solution is required for the 2.4 GHz ISM band. The 4-pole architecture offers superior selectivity compared to lower-order filters. Consider the physical size constraints of the N-Type inline module against available rack or panel space. Evaluate whether the 2 dB insertion loss meets the system link budget requirements for the specific wireless network topology.

Part Context

This part belongs to the L-com HyperLink series of RF filters. It is distinct from multi-channel variants like the BPF24-806, which handles six channels simultaneously. The BPF24-401 focuses on isolating a single Wi-Fi channel to minimize adjacent channel interference in dense deployment scenarios.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if generic 2.4 GHz bandpass filters meet the specific 4-pole ultra-high Q performance requirements before considering alternatives.
