KFF6449A

Overview

The KFF6449A is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates within a frequency range of 1525 MHz to 1559 MHz, with a center frequency of approximately 1.542 GHz. The component supports an average power handling of 1 W and a peak power of 10 W. Maximum insertion loss is specified at 2.5 dB. The physical dimensions are 11.9 mm in length, 8.9 mm in width, and 4.5 mm in height.

Feature Summary

• Utilizes multi-layer ceramic technology for electromagnetic compatibility suppression
• Designed as a surface mount monoblock component
• Provides bandpass signal conditioning within the L-band spectrum

Applications

• L-band communication systems requiring frequency filtering
• RF signal conditioning circuits
• Electromagnetic interference suppression in electronic assemblies

Procurement Notes

Verify the specific datasheet version before procurement, as Tusonix offers diverse standard and custom variations. Confirm that the monoblock surface mount package aligns with your PCB footprint requirements. Ensure the 1 W average power rating meets your system's thermal and electrical constraints. Check for any RoHS compliance status updates directly from the manufacturer documentation.

Selection Notes

Select this component when a fixed ceramic bandpass filter is required for L-band applications. The 11.9x8.9x4.5 mm form factor suits space-constrained surface mount designs. Consider the 2.5 dB maximum insertion loss against system link budget requirements. Verify that the 10 W peak power capability exceeds transient signal levels in the target application environment.
