Overview
The ZVBP-3R25G-S+ is a coaxial cavity band pass filter manufactured by Mini-Circuits. It operates within a frequency range of 3 to 3.5 GHz with a center frequency of 3.25 GHz and a bandwidth of 500 MHz. The component features a 50 Ohm impedance and utilizes SMA connectors. Typical performance specifications include an insertion loss of 0.3 dB and a return loss of 20 dB. It is designed for narrow-band applications requiring high Q resonant structures.
Feature Summary
- Coaxial cavity construction utilizing resonant structures with very high Q factors
- Designed specifically for narrow-band signal conditioning applications
- Provides good rejection characteristics outside the passband
Applications
- Narrow-band RF signal conditioning
- Communication systems requiring specific frequency filtering
- Test and measurement equipment
Procurement Notes
Verify the connector type against the official datasheet, as variations may exist. Confirm that the operating temperature range of -40 C to +85 C meets your environmental requirements. Ensure the SMA interface matches your system design. Cross-reference the part number suffix to confirm exact specifications before procurement.
Selection Notes
Select this component when a narrow-band filter with low insertion loss is required in the 3 to 3.5 GHz range. The high Q factor makes it suitable for applications demanding sharp cutoff characteristics. Consider the physical mounting constraints associated with coaxial cavity filters compared to planar alternatives.
Part Context
This part belongs to Mini-Circuits' ZVBP series of cavity band pass filters. These components are engineered for robust performance in RF environments. The series typically offers high power handling and stability. The ZVBP-3R25G-S+ represents a specific configuration optimized for the 3.25 GHz center frequency.
Replacement Considerations
Consult the official Mini-Circuits substitution guide for verified equivalents. Generic replacements may not match the specific Q factor or rejection profile. Verify impedance and connector compatibility before substituting.
