CER0286A

Overview

The CER0286A is a ceramic RF duplexer manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates within the 1.71 to 1.88 GHz frequency range and supports a power handling capacity of 3 W. The device features two distinct bands: Band 1 covers 1.81 to 1.88 GHz, while Band 2 spans 1.71 to 1.79 GHz. Constructed as a monoblock unit with a three-pad configuration, it serves as a compact solution for RF signal separation in communication systems requiring precise frequency isolation.

Feature Summary

Monoblock ceramic construction for structural integrity
Dual-band operation supporting specific frequency ranges
Three-pad pad configuration for mounting

Applications

RF signal separation in communication modules
Frequency isolation in transceiver circuits
Wireless infrastructure components

Procurement Notes

Verify manufacturer authenticity through official CTS/Tusonix channels. Confirm datasheet version matches current production specifications. Ensure environmental compliance documentation aligns with project requirements. Cross-reference part numbers to avoid confusion with similar series components. Validate technical parameters against system design constraints before procurement.

Selection Notes

Evaluate frequency band alignment with system requirements. Assess power handling capabilities relative to operational loads. Consider physical dimensions and mounting interface compatibility. Review thermal performance characteristics for integration stability. Compare isolation specifications against interference mitigation needs.

Part Context

This component belongs to the CER series of ceramic filters produced by Tusonix. These devices are designed for high-frequency applications requiring reliable signal filtering. The series utilizes ceramic materials to achieve stable performance across varying environmental conditions.
