XRA10AA20SES

Overview

The XRA10AA20SES is a surface-mount chip attenuator manufactured by TTM Technologies. It provides a fixed attenuation of 20 dB with a frequency range from DC to 6 GHz. The component operates at a 50 Ohm impedance and supports a power rating of 10 Watts. It utilizes Aluminum Nitride (AIN) technology for thermal stability. The device is housed in a 3-SMD, no-lead package suitable for SMD/SMT installation. It functions within an operating temperature range of -55°C to +150°C.

Feature Summary

• Fixed 20 dB attenuation value across the operational bandwidth
• High power handling capability of 10 Watts using AIN substrate
• Wide frequency response extending from DC to 6 GHz
• Surface-mount design compatible with automated assembly processes

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise signal reduction
• Microwave circuitry for signal level adjustment
• Broadband RF front-end modules

Procurement Notes

Verify the specific suffix 'SES' against the manufacturer's current datasheet to confirm package dimensions and termination style. Ensure the required 20 dB attenuation aligns with system design specifications. Confirm that the 10W power rating and 6 GHz frequency limit meet application requirements. Check RoHS compliance status directly with the supplier documentation before finalizing procurement orders.

Selection Notes

Select this component when a fixed 20 dB reduction is required in high-power RF environments up to 6 GHz. The 50 Ohm impedance matches standard transmission lines. Consider the 3-SMD footprint for PCB layout constraints. Verify thermal management capabilities given the 10W rating and AIN construction. Compare against other values in the XRA10 series if different attenuation levels are needed.

Part Context

This part belongs to the XRA10 series of chip attenuators from TTM Technologies. The series includes various attenuation values such as 1 dB, 5 dB, and 10 dB, all sharing similar power and frequency characteristics. The XRA10AA20SES specifically denotes the 20 dB variant within this family, maintaining consistent packaging and electrical performance standards across the line.

Replacement Considerations

Direct substitutes include other XRA10 series variants like XRA10AA10SES or XRA10AA5SES if lower attenuation is acceptable. Cross-reference with Anaren Wireless equivalents if available. Verify pinout compatibility and thermal resistance metrics before swapping components in existing designs.
