VAT-30A+

Overview

The VAT-30A+ is a fixed attenuator from Mini-Circuits designed for RF and microwave applications. It provides a nominal attenuation of 30 dB across a frequency range of DC to 6 GHz. The device features SMA connectors, with an SMA male connector on one end and an SMA female connector on the other, facilitating in-line module integration. It operates within a maximum input power of 1 Watt and maintains a characteristic impedance of 50 Ohms. The unit is constructed using silicon technology and is rated for operation temperatures ranging from -45°C to +85°C.

Feature Summary

• Fixed 30 dB attenuation with excellent flatness across the wideband DC to 6 GHz range
• SMA male to SMA female connector configuration for versatile in-line installation
• High power handling capability up to 1 Watt maximum input power
• Robust performance with low VSWR ensuring signal integrity

Applications

• RF signal level reduction in communication systems
• Impedance matching and isolation in test and measurement setups
• Signal conditioning in wireless infrastructure equipment
• Attenuation stages in microwave circuit design

Procurement Notes

Verify the specific datasheet version provided by the manufacturer or authorized distributor to confirm current specifications. Ensure compatibility with system impedance requirements of 50 Ohms. Check connector gender orientation (SMA Male to Female) against schematic designs. Confirm thermal operating limits align with application environment constraints before procurement.

Selection Notes

Select the VAT-30A+ when a precise 30 dB attenuation is required at frequencies up to 6 GHz. Consider its 1W power rating for moderate power levels. The SMA interface suits standard benchtop or modular RF designs. Evaluate alternative attenuation values if the required loss differs significantly from 30 dB.

Part Context

This component belongs to the VAT-A series of fixed attenuators manufactured by Mini-Circuits. The series offers various attenuation values including 3, 6, 10, 20, and 30 dB options. These devices are engineered for wideband performance and are commonly used in RF signal processing chains where stable attenuation is critical.

Replacement Considerations

Direct substitutes include other VAT-A series models with identical form factors but different attenuation values, such as VAT-20A+ or VAT-10A+, if lower loss is acceptable. Cross-reference with other manufacturers' 30dB SMA attenuators rated for DC-6GHz if supply chain adjustments are necessary.
