YAT-1A+

Overview

The YAT-1A+ is a fixed attenuator from the YAT-A series by Mini-Circuits, designed for RF and microwave applications. It operates over a frequency range of DC to 18 GHz with an impedance of 50 Ohms. The device supports a maximum power handling of 2 Watts and maintains a maximum VSWR of 1.7. It functions within a temperature range up to +85 C. The component is housed in a 6-VDFN exposed pad package and complies with ROHS3 standards.

Feature Summary

• Compact surface-mount design suitable for high-density PCB layouts
• Broadband operation extending from DC to 18 GHz
• Robust power handling capability for signal attenuation tasks

Applications

• RF signal path attenuation in communication systems
• Impedance matching and level control in microwave circuits
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific attenuation value required, as the YAT-A series offers various options from 0 to 30 dB. Confirm the exact package variant matches the 6-VDFN exposed pad specification. Ensure compliance with ROHS3 requirements for environmental regulations. Check thermal management needs against the +85 C maximum operating limit. Validate that the 2W power rating suffices for the intended application load.

Selection Notes

Select this component when broadband attenuation up to 18 GHz is necessary. Consider the 50 Ohm impedance compatibility with standard RF systems. Evaluate the 2W power capacity against peak signal levels. The compact footprint aids in space-constrained designs. Verify thermal dissipation capabilities for continuous operation near maximum ratings.

Part Context

The YAT-1A+ belongs to Mini-Circuits' YAT-A series of fixed attenuators. This series provides reliable signal reduction across wide bandwidths. The components are engineered for consistent performance in demanding RF environments. They support modern wireless infrastructure and test instrumentation needs.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 18 GHz frequency range, 50 Ohm impedance, and 6-VDFN package dimensions. Verify equivalent power handling and VSWR specifications before substitution.
