CSBP-D1189+

Overview

The Mini-Circuits CSBP-D1189+ is a ceramic bandpass filter with a center frequency of 1.189 GHz and a bandwidth of 116 MHz, operating within the 1130 to 1246 MHz range. It features a 50-ohm impedance and an insertion loss of 2 dB. The component utilizes a 14-SMD module package measuring 22.35 mm in length, 15.88 mm in width, and 5.72 mm in maximum height. Designed for surface mount installation, it complies with RoHS3 standards and carries an EAR99 classification.

Feature Summary

• Utilizes ceramic-coaxial-resonator technology for high performance
• Provides outstanding close-in rejection capabilities
• Ensures low insertion loss for efficient signal transmission

Applications

• RF signal conditioning circuits
• Bandpass filtering in microwave systems
• Surface mount integration in communication hardware

Procurement Notes

Verify the specific ordering suffix and package configuration against the official Mini-Circuits datasheet before procurement. Confirm that the 14-SMD module dimensions align with the target PCB layout constraints. Ensure compliance with RoHS3 requirements and check the standard lead time of approximately 18 weeks for availability planning. Cross-reference the part number with authorized distributors to ensure authenticity.

Selection Notes

Select this component when a precise 1.189 GHz center frequency with a 116 MHz bandwidth is required. The 50-ohm impedance matches standard RF system designs. Consider the 14-SMD surface mount package for automated assembly processes. Evaluate the 2 dB insertion loss against system sensitivity requirements. Verify that the physical footprint fits within the available board space constraints.

Part Context

This component belongs to the Mini-Circuits ceramic filter series, which offers various bandpass solutions. The CSBP-D1189+ specifically addresses applications requiring robust filtering at UHF frequencies. It is distinct from MMIC components and bare die options provided by the manufacturer. The product line emphasizes reliable signal conditioning for professional electronic systems.

Replacement Considerations

Consult the official Mini-Circuits documentation for direct substitute part numbers. Verify that any alternative maintains the 1.189 GHz center frequency and 116 MHz bandwidth specifications. Ensure the replacement supports the same 50-ohm impedance and 14-SMD package type. Check for compatibility with existing PCB footprints and thermal management requirements.
