ATS1005-9DB-FD-T1

Attenuators Overview

The ATS1005-9DB-FD-T1 is a high-frequency chip attenuator manufactured by Susumu, designed for surface-mount applications in the 0402 (1005 metric) package. It provides a nominal attenuation of 9 dB with a tolerance of ±2 dB at a characteristic impedance of 50 Ohms. The device operates across a frequency range from DC to 50 GHz, supporting a maximum power rating of 32 mW. Key electrical specifications include a maximum Voltage Standing Wave Ratio (VSWR) of 1.4 and 1.6.

Attenuators Feature Summary

• Thin-film construction ensures stable performance across a wide frequency spectrum up to 50 GHz.
• Miniature 0402 footprint allows for dense layout integration in compact RF circuits.
• Designed for high-reliability signal attenuation in wireless communication environments.

Attenuators Applications

• Cell phone base stations
• Wireless communication modules
• RF test and measurement equipment

Attenuators Procurement Notes

Verify the specific ordering suffix 'FD' against the manufacturer's current datasheet to confirm pinout and termination compatibility. Confirm that the required attenuation tolerance aligns with the standard ±2 dB specification provided for this series. Ensure the PCB land pattern matches the 0402 (1005 metric) dimensions to guarantee proper solder joint formation during assembly.

Attenuators Selection Notes

Select this component when a fixed 9 dB attenuation is required within a 50 Ohm system operating up to 50 GHz. Consider the 32 mW power limit for signal levels exceeding -15 dBm. Evaluate the 0402 package size against available board space constraints compared to larger series like ATS2012 if higher power handling is needed.

Attenuators Part Context

This part belongs to the ATS1005 series of high-frequency chip attenuators from Susumu. The series offers various attenuation values ranging from 0 dB to 10 dB in the same miniature form factor. These components are engineered for use in modern wireless infrastructure where space-saving SMD solutions are critical for maintaining signal integrity at microwave frequencies.

Attenuators Replacement Considerations

Direct substitutes within the same series include ATS1005-7DB-FD-T1 and ATS1005-10DB-FD-T1 for different attenuation requirements. Cross-series replacements such as the PXV1220S-6DBN2-T offer similar functionality but differ in package size (1210 vs 0402) and power rating, requiring layout adjustments.
