KFF6450A

Overview

The KFF6450A is a surface-mount band pass ceramic filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for InMarSat applications, this silver-coated ceramic component operates at a center frequency of 1643.5 MHz with a bandwidth of 34 MHz. It exhibits an insertion loss of approximately 1.36 dB to 2.2 dB and has a maximum operating temperature of +85°C. The device is supplied in reel packaging and weighs approximately 1.2 grams.

Feature Summary

• Surface mount construction utilizing silver-coated ceramic technology
• Engineered specifically for InMarSat communication applications
• Band pass filtering capability centered at 1643.5 MHz

Applications

• InMarSat satellite communication systems
• RF signal filtering in marine satellite receivers
• Band pass filtering for L-band frequencies

Procurement Notes

Verify the manufacturer designation carefully, as sources list both Tusonix and CTS Electronic Components due to their subsidiary relationship. Confirm the specific insertion loss value required for your design, as documentation varies between 1.36 dB and 2.2 dB. Ensure the surface mount package dimensions align with your PCB layout constraints before ordering.

Selection Notes

Select this component when a dedicated band pass filter for InMarSat frequencies is required. The surface mount format suits automated assembly processes. Consider the thermal rating of +85°C for environmental compatibility. Verify that the 34 MHz bandwidth meets the system's spectral requirements for the 1643.5 MHz center frequency.

Part Context

This part belongs to the family of ceramic band pass filters produced by Tusonix/CTS. These components are specialized RF devices intended for high-frequency communication links. The KFF6450A represents a specific solution for satellite navigation and communication bands, distinct from general-purpose LC or SAW filters.
