ATS1005-9DB-FD-T05

Attenuators Overview

The ATS1005-9DB-FD-T05 is a high-frequency chip attenuator manufactured by Susumu. It provides a fixed attenuation of 9 dB with a nominal impedance of 50 ohms. The device operates within a frequency range from DC to 50 GHz and has a maximum power rating of 32 mW. It features a maximum VSWR of 1.6 and is housed in a compact 0402 (1005 metric) surface-mount package. The component supports an operating temperature range from -40 °C to +125 °C.

Attenuators Feature Summary

• High-frequency operation extending up to 50 GHz for wideband signal processing
• Compact 0402 surface-mount footprint suitable for space-constrained PCB layouts
• Fixed 9 dB attenuation value ensuring consistent signal level reduction

Attenuators Applications

• RF signal path conditioning in wireless communication systems
• Test and measurement equipment requiring precise signal attenuation
• High-frequency circuit boards needing stable impedance matching

Attenuators Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct attenuation value and tolerance specifications. Confirm that the required frequency range and power handling capabilities align with the specific application constraints before ordering. Cross-reference the package dimensions with the mechanical drawing to validate board space requirements.

Attenuators Selection Notes

Select this component when a fixed 9 dB attenuation is required at frequencies up to 50 GHz. Ensure the design accommodates the 32 mW power limit and the specified operating temperature range. Compare the 0402 package size against available board real estate and verify compatibility with standard SMT assembly processes for thin-film resistors.

Attenuators Part Context

This part belongs to the Susumu ATS1005 series of high-frequency chip attenuators. The series offers various attenuation values within a 0 to 10 dB range, all supporting DC to 50 GHz operation. These components utilize thin-film technology to maintain performance stability across wide bandwidths and varying environmental conditions.

Attenuators Replacement Considerations

Direct substitutes include other ATS1005 series variants with different attenuation values if system requirements change. Verify that any alternative maintains the same 50-ohm impedance and 0402 package dimensions to ensure mechanical and electrical compatibility without redesigning the footprint.
