BPF24-809A

Overview

The L-com BPF24-809A is an outdoor bandpass filter designed for the 2.4 GHz ISM band, specifically tuned to Channel 9 with a center frequency of 2452 MHz. This 8-pole unit features a 22 MHz bandwidth and utilizes N-Type connectors for inline signal conditioning. It exhibits a passband ripple of 0.25 dB and an insertion loss of 3 dB. The device is engineered for high Q-value performance in external wireless infrastructure applications requiring precise frequency selection.

Feature Summary

• Eight-pole filter architecture providing steep skirt selectivity for superior out-of-band rejection
• Outdoor-rated construction suitable for harsh environmental conditions and permanent installation
• High Q-value design ensuring minimal signal degradation within the specified passband

Applications

• Wireless LAN (WLAN) base station filtering
• Point-to-point microwave link signal conditioning
• Outdoor wireless bridge interference mitigation

Procurement Notes

Verify that the specific order matches the BPF24-809A designation to ensure the correct Channel 9 tuning. Confirm connector gender and cable length requirements if applicable. Ensure the procurement documentation references the manufacturer's official specifications for insertion loss and VSWR limits before finalizing the purchase agreement.

Selection Notes

Select this component when Channel 9 isolation is required for 2.4 GHz systems. The 8-pole configuration offers better attenuation than lower-order filters. Verify that the system power levels remain within the filter's linear range to prevent intermodulation distortion. Ensure the N-Type interface compatibility with existing cabling infrastructure.

Part Context

This model belongs to L-com's FIL series of RF bandpass filters. It shares the same physical form factor and connector type as other units in the BPF24-8xxA family, differing primarily in the tuned center frequency and channel assignment. The series provides standardized solutions for various global regulatory channels within the 2.4 GHz spectrum.

Replacement Considerations

Direct substitutes include other BPF24-8xxA models from L-com if a different channel frequency is acceptable. Cross-brand replacements require matching the 8-pole topology, N-Type interface, and 22 MHz bandwidth to maintain system performance characteristics.
