Procurement Notes

Verify the specific ordering suffix and package variant against the official Mini-Circuits datasheet before procurement. Confirm that the component meets the required environmental specifications, including RoHS3 compliance and EAR99 classification. Ensure the selected quantity aligns with standard packaging requirements and check for any recent product change notices affecting internal circuitry or capacitor lots.

Selection Notes

Select this component when a fixed center frequency of 1.843 GHz and a 155 MHz bandwidth are required for 50-ohm systems. Consider the 16-SMD module footprint for space-constrained PCB layouts. Evaluate the 2.5 dB insertion loss against system link budget requirements. Ensure compatibility with surface-mount assembly processes and verify thermal management needs for the specified operating environment.

Part Context

This part belongs to the Mini-Circuits CSBP series of ceramic bandpass filters. These components are engineered for high-reliability RF applications requiring precise frequency selection. The series offers various center frequencies and bandwidths to support diverse communication standards. The CSBP-A1843+ specifically targets the 1.8 GHz ISM band region for specialized filtering tasks.

Replacement Considerations
