ACFF-1025-TR1

Overview

The ACFF-1025-TR1 is a surface-mount bandpass RF filter manufactured by Broadcom Limited. It features a center frequency of 2.49925GHz and a bandwidth of 5.5MHz. The component exhibits an insertion loss of 4dB and operates with a nominal impedance of 50 ohms for both input and output. It is housed in a compact 3-SMD, no-lead package measuring approximately 2.50mm x 2.50mm with a maximum height of 1.10mm. The device supports an average input power of 1.995W.

Feature Summary

• Provides precise signal selection within the specified radio frequency band
• Designed for surface-mount integration into compact electronic assemblies
• Maintains standard 50-ohm impedance matching for system compatibility

Applications

• Wireless communication systems requiring specific frequency filtering
• RF front-end modules in consumer electronics
• Signal processing circuits operating at 2.49925GHz

Procurement Notes

Verify the exact part number suffix to ensure correct packaging configuration, as variants such as TR1 indicate tape-and-reel delivery. Confirm that the required center frequency and bandwidth align with the design specifications before procurement. Ensure the supplier provides authentic components from Broadcom Limited or authorized distributors to guarantee performance reliability and avoid counterfeit risks.

Selection Notes

Select this component when a fixed center frequency of 2.49925GHz is required rather than tunable alternatives. Consider the 3-SMD package dimensions for PCB layout constraints. Evaluate the 4dB insertion loss against system sensitivity requirements. Ensure the 1.995W power handling capability meets the operational signal levels of the target application circuit.

Part Context

This component belongs to Broadcom's portfolio of radio frequency filters designed for modern wireless applications. It serves as a passive element for frequency discrimination in RF chains. The product line emphasizes miniaturization and high performance for mobile and IoT devices. Broadcom utilizes advanced materials to achieve stable filtering characteristics across varying environmental conditions.

Replacement Considerations

Cross-reference with other Broadcom ACFF series parts if different bandwidths are needed. Verify pinout compatibility for direct replacement. Check datasheets for equivalent filters from other manufacturers ensuring identical 2.49925GHz center frequency and 50-ohm impedance.
