KFF6138A

Overview

The KFF6138A is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for RF signal conditioning, this component operates with a center frequency of 1.03 GHz. It features a bandwidth of 6 MHz and an insertion loss of 1.7 dB. The device utilizes surface mount technology (SMD/SMT) termination styles. Physical dimensions are specified as 33.58 mm x 10.744 mm x 7.85 mm. The product status is active, and it falls under the passive components category within the ceramic filters subcategory.

Feature Summary

• Ceramic construction for stable RF filtering performance
• Bandpass configuration centered at 1.03 GHz
• Surface mount design for automated assembly integration

Applications

• RF signal conditioning in communication systems
• Frequency selection in wireless transceivers
• Intermediate frequency filtering in receiver architectures

Procurement Notes

Verify part authenticity through authorized CTS distributors. Confirm RoHS compliance status as documentation indicates no specific information. Ensure surface mount compatibility with PCB layout specifications. Check patent coverage details if intellectual property constraints apply to your design implementation.

Selection Notes

Select this component when a 1.03 GHz center frequency with 6 MHz bandwidth is required. Consider the 1.7 dB insertion loss impact on system noise figure. Evaluate the large physical footprint against available board space. Verify SMD termination suitability for your manufacturing process capabilities.

Part Context
