ZVBP-323-S+

Overview

The ZVBP-323-S+ is a coaxial cavity band pass filter manufactured by Mini-Circuits, designed for RF signal conditioning applications. It operates within a frequency range of 300 to 346 MHz with a center frequency of 323 MHz and a bandwidth of 46 MHz. The component features a 50 Ohm impedance and utilizes SMA connectors for inline module integration. Typical performance specifications include an insertion loss of 0.2 dB, a return loss of 22 dB, and rejection capabilities reaching 80 dB.

Feature Summary

• High Q resonant structures implemented via coaxial cavity design
• Low insertion loss characteristics for efficient signal transmission
• Superior out-of-band rejection performance

Applications

• RF signal conditioning in communication systems
• Interference filtering in receiver front ends
• Spectrum management in broadcast equipment

Procurement Notes

Verify the specific datasheet version and mechanical dimensions against your PCB layout requirements before procurement. Confirm that the SMA connector polarity and mating interface match your system cabling. Ensure environmental operating conditions align with the component's specified temperature range. Cross-reference the part number suffix to confirm the exact termination style and packaging configuration required for your assembly process.

Selection Notes

Select this component when high selectivity and low loss are critical within the 300-346 MHz range. The coaxial cavity construction offers superior stability compared to planar filters. Consider the physical size constraints as cavity filters typically require more board space than surface-mount alternatives. Evaluate the need for high rejection levels to mitigate adjacent channel interference in dense spectral environments.

Part Context

This model belongs to Mini-Circuits' ZVBP series of cavity band pass filters. These components are engineered for robust performance in demanding RF environments. The series provides various center frequencies while maintaining consistent electrical characteristics such as low insertion loss and high power handling capabilities suitable for commercial and industrial applications.

Replacement Considerations

Direct substitutes may include other Mini-Circuits cavity filters with similar center frequencies and bandwidths, such as the ZVBP-3260-S+ for higher frequency ranges or models from the same family with adjusted passbands. Verify mechanical compatibility and connector types when considering alternative manufacturers.
