VAT-4A+

Overview

The VAT-4A+ is a fixed attenuator from Mini-Circuits designed for RF applications. It provides a nominal attenuation of 4 dB across a frequency range of DC to 6000 MHz (6 GHz). The component operates with a characteristic impedance of 50 Ohms and features SMA connectors for in-line module integration. It has a power handling capability of up to 1.7W. The device utilizes a rugged construction suitable for demanding environments.

Feature Summary

• Fixed 4 dB attenuation value
• Wideband operation from DC to 6 GHz
• SMA connector interface
• Rugged in-line module design

Applications

• RF signal level adjustment
• Impedance matching networks
• Test and measurement equipment
• Communication systems

Procurement Notes

Verify the specific datasheet version for the VAT-4A+ to confirm mechanical dimensions and connector details, as generic photos may vary. Ensure the required power rating of 1.7W aligns with system specifications. Check for any ordering suffixes that might indicate different packaging or testing standards. Confirm availability through authorized distributors to guarantee authenticity.

Selection Notes

Select the VAT-4A+ when a precise 4 dB reduction is needed within the 6 GHz bandwidth. Consider the SMA interface compatibility with existing circuitry. Evaluate the 1.7W power limit against peak signal levels. Compare with other Mini-Circuits attenuators if different attenuation values or frequency ranges are required.

Part Context

Mini-Circuits manufactures a broad range of RF components. The VAT series includes various fixed attenuator models. The VAT-4A+ is part of this lineup, offering standard attenuation values. These components are widely used in microwave and radio frequency engineering.

Replacement Considerations

The VAT-4+ is a similar model from Mini-Circuits. Verify connector types and exact specifications before substitution. Other manufacturers offer equivalent 4 dB attenuators; ensure impedance and frequency range match.
