VAT-8A+

Overview

The VAT-8A+ is a fixed attenuator from Mini-Circuits designed for RF and microwave applications. It provides an attenuation value of 8 dB with a frequency range spanning from DC to 6000 MHz. The component features SMA male and female connectors, ensuring versatile interconnectivity. It operates within a 50 Ohm impedance system and supports a maximum input power of up to 2 Watts. The unit exhibits excellent VSWR performance, typically ranging between 1.20:1 and 1.45:1. Designed for robust operation, it functions reliably within a temperature range of -45°C to +100°C. The device is housed in a compact FF704 case style, measuring approximately 36.32 mm in length.

Feature Summary

• Wideband operation from DC to 6000 MHz with excellent attenuation flatness
• High power handling capability supporting up to 2W input
• Low VSWR characteristics ensuring minimal signal reflection
• SMA connector interface for reliable in-line integration

Applications

• RF test and measurement equipment
• Microwave communication systems
• Signal level reduction in receiver chains
• Calibration and verification setups

Procurement Notes

Verify the specific suffix and manufacturer documentation before procurement. Confirm that the VAT-8A+ meets the required power and frequency specifications for the intended application. Check for any discontinuance notifications or alternative part numbers if supply chain constraints exist. Ensure compatibility with existing SMA connector interfaces in the design.

Selection Notes

Select the VAT-8A+ when an 8 dB fixed attenuation is required across a wide bandwidth up to 6 GHz. Consider its 2W power rating for high-power signal paths. Evaluate the SMA connector type against system interface requirements. Assess the thermal operating range to ensure suitability for the environmental conditions of the deployment.

Part Context

The VAT-8A+ belongs to the VAT-A series of fixed attenuators manufactured by Mini-Circuits. This series is characterized by wideband performance and low VSWR. The component serves as a passive RF element used to reduce signal amplitude without introducing significant distortion. It is part of a broader family of attenuators offering various attenuation values within the same form factor.

Replacement Considerations

Check Mini-Circuits official documentation for direct substitutes. Verify that any replacement maintains the 8 dB attenuation value and 50 Ohm impedance. Ensure the substitute supports the same SMA connector configuration and power handling capabilities.
