XRA10AA1SES

Overview

The XRA10AA1SES is a surface-mount RF attenuator manufactured by TTM Technologies. It provides a nominal attenuation of 1 dB with a tolerance of 0.25 dB across a frequency range from 0 Hz to 6 GHz. The component operates at a 50 Ohm impedance and supports a power rating of 10 Watts. It utilizes a 2-SMD, no-lead package design suitable for automated assembly.

Feature Summary

• Provides precise 1 dB signal attenuation for RF circuitry
• Operates effectively from DC up to 6 GHz frequencies
• Supports high power handling capabilities of 10 Watts
• Features a compact surface-mount package for PCB integration

Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks in microwave circuits
• Signal level adjustment in test and measurement equipment
• Attenuation stages in radar and electronic warfare systems

Procurement Notes

Verify the specific manufacturer part number against official TTM Technologies documentation to ensure authenticity. Confirm that the requested quantity aligns with standard factory packaging requirements. Check for any recent product change notices regarding material or process updates. Ensure compliance with relevant export control classifications if applicable to your region.

Selection Notes

Select this component when a low attenuation value near 1 dB is required within a 6 GHz bandwidth. Consider its 10 Watt power rating for high-power applications. Evaluate the 2-SMD footprint compatibility with existing PCB layouts. Compare performance against other series members like XRA10AA5SES or XRA10AA10SES if different attenuation levels are needed.

Part Context

This part belongs to the XRA10 series of chip attenuators from TTM Technologies. The series offers various attenuation values including 1, 3, 5, 10, and 20 dB options. These components share similar power handling and frequency characteristics but differ in attenuation precision and physical package dimensions depending on the specific model variant selected.

Replacement Considerations

Direct substitutes include other XRA10 series variants such as XRA10AA3SES or XRA10AA5SES if higher attenuation is acceptable. Verify pinout and thermal characteristics before swapping. No direct cross-brand equivalents are confirmed in public data.
