BPF900A

Overview

The L-com BPF900A is a four-pole outdoor bandpass RF filter designed for rugged applications. It operates at a center frequency of 915MHz with a bandwidth of 35MHz, covering the 902MHz to 928MHz range. The module features a maximum insertion loss of 0.5dB and ripple of 0.25dB. Constructed from aluminum, it measures 74.00mm x 74.00mm x 50.00mm and utilizes N-type female connectors.

Feature Summary

• Four-pole full-band design for effective signal filtering
• Rugged aluminum construction suitable for harsh outdoor environments
• Low insertion loss and ripple characteristics for signal integrity

Applications

• GSM communication systems
• ISM band operations
• RFID infrastructure
• SCADA networks

Procurement Notes

Verify the specific connector type and mounting configuration against project requirements before ordering. Confirm that the 915MHz center frequency aligns with local regulatory bands for ISM or RFID usage. Ensure the N-type female interface matches existing cabling infrastructure to avoid adapter-related losses.

Selection Notes

Select this component when a robust, weather-resistant filter is required for 900MHz band applications. The aluminum housing provides durability for outdoor deployment. Consider the physical dimensions and base-mount installation style during system integration planning to ensure adequate clearance and secure attachment.

Part Context
