ZX75BP-1250-S+

Overview

The ZX75BP-1250-S+ is a ceramic resonator bandpass RF filter manufactured by Mini-Circuits. It operates with a center frequency of 1.25 GHz and a bandwidth of 70 MHz. The component features an insertion loss of 2 dB and maintains a 50 Ohm impedance. It utilizes SMA connectors for inline installation and is housed in the HY1238 case style.

Feature Summary

• Utilizes ceramic resonator technology for stable bandpass filtering performance
• Designed for inline signal conditioning within radio frequency circuits
• Provides defined bandwidth selection centered at 1.25 GHz

Applications

• Radio frequency signal processing systems
• Intermediate frequency filtering applications
• Communication equipment signal conditioning

Procurement Notes

Verify the specific datasheet revision to confirm electrical parameters match design requirements. Ensure SMA connector compatibility with existing circuit interfaces. Confirm RoHS compliance status if required by manufacturing standards. Check lead times as production cycles may vary significantly from standard estimates.

Selection Notes

Select this component when a narrow 70 MHz bandwidth is required at 1.25 GHz. The 2 dB insertion loss offers moderate efficiency for general RF applications. The SMA interface simplifies integration into test setups or modular systems requiring standard coaxial connections.

Part Context

This part belongs to the ZX75BP series, which comprises ceramic resonator bandpass filters. These components are engineered for consistent performance across various RF and IF stages. The series provides multiple center frequency options while maintaining uniform mechanical and electrical characteristics.

Replacement Considerations

Direct substitutes include other ZX75BP models with adjusted center frequencies such as ZX75BP-1500-S+ or ZX75BP-4700-S+. Verify that alternative parts maintain the same 50 Ohm impedance and SMA connector type to ensure physical and electrical compatibility.
