CER0472A

Overview

The CER0472A is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for surface mount applications, this monoblock component operates within the 885 MHz to 909 MHz frequency range. It functions as a signal conditioning device, specifically categorized as a SAW duplexer in some documentation contexts. The unit utilizes an SMD/SMT termination style for integration into printed circuit boards. This component is part of the CER series and is intended for RF applications requiring precise frequency selection within the specified band.

Feature Summary

• Surface mount monoblock construction for reliable PCB integration
• Bandpass filtering capability within the 885-909 MHz range
• SAW duplexer functionality for signal conditioning

Applications

• RF signal conditioning circuits
• Wireless communication systems operating in the 885-909 MHz band
• Surface mount assembly processes

Procurement Notes

Verify the specific datasheet version when sourcing, as documentation may refer to the component variously as a ceramic filter or SAW duplexer. Confirm the exact frequency range requirements against the 885 MHz to 909 MHz specification provided by Tusonix/CTS. Ensure compatibility with surface mount assembly techniques given the SMD/SMT termination style. Cross-reference manufacturer part numbers to avoid confusion with similar series components.

Selection Notes

Select the CER0472A when a surface mount ceramic filter is required for the 885-909 MHz band. Consider its monoblock form factor for compact designs. Verify that the SAW duplexer characteristics align with system signal conditioning needs. Ensure the application supports the specified frequency range and surface mount installation method without requiring through-hole alternatives.

Part Context

This component belongs to the CER series of ceramic filters produced by Tusonix, now a subsidiary of CTS Electronic Components. The series includes various models designed for different RF frequency bands. The CER0472A specifically targets the lower microwave frequencies around 900 MHz, serving as a specialized passive component for RF front-end modules in communication equipment.
