VAT-5A+

Overview

The VAT-5A+ is a fixed attenuator from the Mini-Circuits VAT-A series, designed for RF applications spanning DC to 6000 MHz. It provides a precise attenuation value of 5 dB with excellent flatness across the frequency range. The component operates at a 50 Ohm impedance and features SMA connectors for in-line module integration. It supports a power rating of 1.4 W and maintains a maximum VSWR of 1.5. The unit utilizes Si technology and is housed in the FF704 case style, ensuring reliable performance within an operating temperature range of -45 C to +85 C.

Feature Summary

• Provides fixed 5 dB attenuation with excellent flatness from DC to 6000 MHz
• Features SMA connectors for straightforward in-line module installation
• Supports high power handling up to 1.4 W with low VSWR

Applications

• RF signal conditioning in communication systems
• Test and measurement equipment calibration
• Microwave circuit impedance matching networks

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm technical specifications such as power rating and frequency range. Ensure compatibility with system impedance requirements of 50 Ohms. Check connector type consistency with existing infrastructure. Confirm operating temperature limits align with environmental conditions. Validate part number authenticity through authorized channels.

Selection Notes

Select this component when a fixed 5 dB attenuation is required between DC and 6 GHz. Consider the 1.4 W power rating for signal levels within this limit. The SMA interface suits standard coaxial connections. Evaluate the FF704 package size for board space constraints. Verify thermal management needs given the specified operating temperature range.

Part Context
