ZX75BP-750-S+

Overview

The ZX75BP-750-S+ is a lumped LC bandpass filter manufactured by Mini-Circuits, designed for radio frequency signal conditioning. It operates within a passband of 600 MHz to 900 MHz, centered at 750 MHz with a bandwidth of 300 MHz. The component features a 50 Ohm impedance and utilizes SMA connectors for inline installation. Key electrical specifications include an insertion loss of 2.5 dB. The unit is housed in a HY1239 case style, measuring 0.740 inches in length, 0.750 inches in width, and 0.490 inches in maximum height.

Feature Summary

• Lumped LC architecture provides stable bandpass filtering characteristics across the specified frequency range.

Applications

• RF signal conditioning in communication systems
• Frequency selection in wireless infrastructure
• Intermediate frequency filtering in receiver chains

Procurement Notes

Verify the specific datasheet revision and environmental compliance status prior to procurement. Confirm that the SMA connector polarity and mounting orientation align with the system design requirements. Ensure the operating temperature range meets the application's thermal constraints. Cross-reference the part number suffix to confirm the exact configuration matches the intended circuit implementation.

Selection Notes

Select this component when a fixed center frequency of 750 MHz with a 300 MHz bandwidth is required. The 50 Ohm impedance rating must match the surrounding transmission line environment. Consider the physical dimensions of the HY1239 package for board layout compatibility. Evaluate the 2.5 dB insertion loss against the system's power budget and noise figure requirements.

Part Context

This device belongs to the ZX75BP series of lumped LC bandpass filters from Mini-Circuits. The series offers various center frequencies while maintaining consistent impedance and connector types. These components are engineered for reliable performance in RF applications requiring precise frequency selection and harmonic rejection.

Replacement Considerations

Direct substitutes within the same series include ZX75BP-600-S+ and ZX75BP-900-S+. Verify that alternative models maintain the required 50 Ohm impedance and SMA interface compatibility before integration into existing designs.
