CER0138B

Overview

The CER0138B is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates at a center frequency of 1.575 GHz with a bandwidth of 20 MHz. Designed for surface-mount installation in a monolithic package, this component serves as a passive filtering element within electronic circuits. The device is currently active and complies with RoHS3 standards.

Feature Summary

• Provides bandpass filtering functionality centered at 1.575 GHz
• Utilizes monolithic ceramic construction for compact integration
• Supports surface-mount technology for automated assembly

Applications

• GPS receiver front-end filtering
• Satellite navigation signal processing
• Wireless communication systems requiring L-band filtering

Procurement Notes

Verify the specific manufacturer part number against official Tusonix or CTS documentation to ensure authenticity. Confirm that the requested units match the active lifecycle status and RoHS3 compliance requirements. Cross-reference distributor listings with original manufacturer datasheets to validate technical specifications before procurement.

Selection Notes

Select the CER0138B when a narrow 20 MHz bandwidth is required at the 1.575 GHz frequency point. Ensure the design accommodates surface-mount mounting constraints and monolithic package dimensions. Validate impedance matching and insertion loss characteristics against system requirements using official electrical data sheets.

Part Context

This component belongs to the family of ceramic filters produced by Tusonix under CTS Electronic Components. These devices are engineered for high-selectivity applications in RF and microwave frequencies. The product line emphasizes reliability and miniaturization for modern electronic assemblies.

Replacement Considerations

Consult official Tusonix documentation for verified substitute part numbers. Do not assume cross-compatibility with generic ceramic filters without verifying electrical parameters and physical footprint alignment.
