D10AA30Z4

Attenuators Overview

The D10AA30Z4 is a surface-mount RF attenuator manufactured by TTM Technologies. It provides a fixed attenuation of 30 dB with a tolerance of 1.5 dB. The device operates from 0 Hz to 3 GHz (some sources cite up to 4 GHz) and features a nominal impedance of 50 Ohms. It supports a power rating of 10 Watts and maintains a maximum VSWR of 1.25:1. The component utilizes ceramic technology and is housed in a compact 5 mm x 2.5 mm SMD package. It functions within a temperature range of -55°C to +125°C.

Attenuators Feature Summary

• Fixed 30 dB attenuation for precise signal level control
• High power handling capability rated at 10 Watts
• Low voltage standing wave ratio ensuring minimal signal reflection
• Ceramic construction for thermal stability and durability

Attenuators Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise attenuation
• Microwave circuit design for signal level adjustment
• Defense and aerospace electronic subsystems

Attenuators Procurement Notes

Verify the specific frequency limit, as documentation varies between 3 GHz and 4 GHz. Confirm the package dimensions against the 5 mm x 2.5 mm specification. Ensure the 10W power rating aligns with thermal management requirements. Check RoHS compliance status directly with the manufacturer. Validate the 1.5 dB tolerance meets circuit precision needs.

Attenuators Selection Notes

Select this component when a high-power, fixed 30 dB attenuation is required in an SMD form factor. Consider the wide operating temperature range for harsh environments. Compare the 1.25:1 VSWR against system return loss requirements. Evaluate the ceramic material properties for thermal conductivity needs. Ensure the 50 Ohm impedance matches the transmission line characteristics.

Attenuators Part Context

This part belongs to the D10AA series of surface-mount attenuators from TTM Technologies. It shares the same physical footprint and power handling characteristics as other variants in the family, such as the D10AA10Z4, but differs in its specific attenuation value. The series is designed for integration into compact RF modules where space constraints and thermal performance are critical factors.
