ZX75BP-1280-S+

Overview

The ZX75BP-1280-S+ is a ceramic resonator band pass filter manufactured by Mini-Circuits. It operates within a frequency range of 1170 MHz to 1390 MHz, centered at 1280 MHz. The device features a 220 MHz bandwidth and maintains a 50 Ohm impedance. It utilizes SMA connectors for inline installation and exhibits an insertion loss of 2 dB. The component is designed for board mounting applications in RF signal conditioning systems.

Feature Summary

• Utilizes coaxial-ceramic resonator technology for stable RF filtering performance
• Provides precise bandpass signal conditioning with defined center frequency
• Features robust SMA connector interface for reliable inline integration

Applications

• RF signal conditioning in communication systems
• Intermediate frequency filtering in wireless networks
• Microwave signal processing in industrial control equipment

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as ZX75BP-B1280-S+ exist within the same family. Confirm that the required impedance matches the standard 50 Ohm specification. Ensure compatibility with SMA connector types for proper physical integration. Cross-reference the exact frequency range against system requirements to avoid mismatched filtering characteristics.

Selection Notes

Select this component when a fixed center frequency of 1280 MHz is required for bandpass filtering. The 220 MHz bandwidth suits applications needing moderate selectivity without complex tuning. Consider the SMA interface if discrete connectorized solutions are preferred over surface mount alternatives. Evaluate thermal stability requirements against the specified operating temperature range.

Part Context

This model belongs to the ZX75BP series of coaxial-ceramic resonator filters produced by Mini-Circuits. The series covers various frequency bands from 1 MHz to 3 GHz. These components are engineered for high-performance RF and IF applications, offering consistent electrical characteristics across wide temperature ranges compared to generic LC filters.

Replacement Considerations

The ZX75BP-B1280-S+ serves as a confirmed substitute variant within the same product family. Both models share identical core specifications including the 1160-1400 MHz frequency range and 50 Ohm impedance. Verify connector type consistency during replacement to ensure mechanical fit.
