VBFZ-4000-S+

Overview

The VBFZ-4000-S+ is a connectorized bandpass filter from Mini-Circuits designed for RF signal conditioning. It operates within a frequency range of 3500 MHz to 4500 MHz, providing a bandwidth of 1000 MHz centered at 4 GHz. The component features a 50-ohm impedance and utilizes SMA connectors for inline integration. It is housed in the FF1145 case style and supports operating temperatures from -55°C to +100°C.

Feature Summary

• Provides selective frequency filtering within the 3500-4500 MHz passband
• Maintains 50-ohm system impedance for standard RF compatibility
• Utilizes SMA connectors for direct coaxial circuit integration

Applications

• RF front-end filtering
• EMI/RFI suppression
• Signal conditioning in communication systems

Procurement Notes

Verify the specific datasheet version and performance graphs directly from Mini-Circuits or authorized distributors before finalizing design specifications. Confirm that the SMA connector orientation and FF1145 package dimensions align with your PCB or chassis layout requirements. Ensure environmental ratings meet the operational temperature extremes of the target application.

Selection Notes

Select this model when a fixed center frequency of 4 GHz with a 1 GHz bandwidth is required. The SMA interface suits applications needing robust mechanical connections rather than surface-mount solutions. Consider the FF1145 form factor for space-constrained inline modules where coaxial continuity is preferred over discrete components.

Part Context

This component belongs to the VBFZ series of connectorized bandpass filters by Mini-Circuits. The series offers various center frequencies and bandwidths using standardized SMA interfaces. These filters are engineered for reliable performance in RF and microwave environments up to several gigahertz.
