1905BP18A0050001E

Overview

The 1905BP18A0050001E is a high-rejection bandpass ceramic filter manufactured by Johanson Technology Inc. It operates with a center frequency of 1.905 GHz and provides a bandwidth of 50 MHz. The component features an insertion loss of 1.65 dB and is designed for a system impedance of 50 Ohms. It utilizes a surface-mount package in the 1206 (3216 metric) dimensions, measuring 3.20 mm in length, 1.60 mm in width, and 1.00 mm in maximum height.

Feature Summary

High rejection performance for improved signal selectivity
Optimized for DECT NR+ and DECT-2020 NR IoT applications
Surface-mount construction for automated assembly

Applications

DECT NR+ systems
DECT-2020 NR IoT devices
DECT 6.0 infrastructure
Legacy DECT equipment

Procurement Notes

Verify the specific suffix 'E' against official Johanson Technology documentation to confirm compliance with current environmental standards and material specifications. Ensure that the ordering information matches the exact part number required for DECT NR+ integration. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain consistent with design requirements before finalizing procurement orders.

Selection Notes

Select this component when designing RF front-ends requiring precise filtering for the 1.9 GHz ISM band. The 1206 footprint offers a balance between performance and board space efficiency. Consider the 1.65 dB insertion loss impact on overall link budget. Verify compatibility with existing PCB land patterns and reflow soldering profiles suitable for ceramic filters.

Part Context

This component belongs to Johanson Technology's BP series of high-rejection bandpass filters. These components are engineered specifically for wireless communication protocols operating in the 1.9 GHz range. The series supports various DECT standards, providing manufacturers with standardized solutions for noise reduction and interference mitigation in compact mobile and base station hardware.

Replacement Considerations

The legacy part number 1905BP18A0050 serves as a direct predecessor. Verify if the 'E' suffix indicates a change in packaging or material composition. No alternative cross-model substitutes are documented in the provided source data.
