ZVBP-1200-S+

Overview

The ZVBP-1200-S+ is a coaxial cavity bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 1.15 GHz to 1.25 GHz with a center frequency of 1.25 GHz. The component features a 50 Ohm impedance and utilizes resonant structures with very high Q factors, making it suitable for narrow-band applications. Typical performance specifications include an insertion loss of 0.6 dB and a return loss of 20 dB.

Feature Summary

• Coaxial cavity construction utilizing high-Q resonant structures
• Designed specifically for narrow-band signal filtering applications
• Provides low insertion loss characteristics
• Ensures good return loss performance

Applications

• Narrow-band RF signal processing
• High-frequency communication systems
• Microwave circuit filtering

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update electrical graphs or mechanical drawings over time. Confirm that the part number suffix matches the required package style. Ensure compatibility with your system's 50 Ohm impedance requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate connector types against your PCB layout or cable assembly specifications before finalizing orders.

Selection Notes

Select this component when a narrow bandwidth around 1.25 GHz is required with minimal signal attenuation. The coaxial cavity design offers superior selectivity compared to planar filters. Consider the physical size constraints, as cavity filters are generally larger than MMIC alternatives. Evaluate the thermal environment, as cavity filters can handle higher power levels than many integrated solutions. Ensure the 50 Ohm system impedance aligns with your overall network design.

Part Context

This component belongs to Mini-Circuits' ZVBP series of coaxial cavity bandpass filters. The series includes various models tuned to different frequency ranges, such as the ZVBP-5310-S+ and ZVBP-6500-S+. These filters are designed to provide high rejection outside the passband while maintaining low loss within the desired frequency window. They are widely used in RF front-end modules where spectral purity is critical.

Replacement Considerations

Direct substitutes must match the 1.15-1.25 GHz frequency range and 50 Ohm impedance. Verify that alternative cavity filters offer comparable insertion loss and return loss specifications. Mechanical footprint compatibility should be confirmed if board space is limited. Ensure the replacement maintains the same mounting style and connector configuration.
