ATS2012-4DB-T1

Attenuators Overview

The ATS2012-4DB-T1 is a high-frequency chip attenuator manufactured by Susumu. It provides a nominal attenuation of 4 dB with a tolerance of +/-0.5 dB. The component operates at a characteristic impedance of 50 Ohms and supports a maximum frequency of 30 GHz. It features a surface-mount package in the 0805 (2012 metric) dimension, specifically sized at 2.0mm x 1.25mm. The device has a power rating of 100 mW and maintains a maximum VSWR of 1.5.

Attenuators Feature Summary

• Thin-film surface-mounted construction for high-frequency stability
• Miniature 0805 footprint suitable for space-constrained designs
• Wideband operation extending up to 30 GHz

Attenuators Applications

• RF signal path attenuation in wireless communication systems
• Impedance matching networks in RF front-end modules
• Test and measurement equipment requiring precise signal reduction

Attenuators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tolerance specifications. Confirm that the 0805 package dimensions align with the target PCB land pattern. Check RoHS compliance status if required by project regulations. Ensure the 100 mW power rating is sufficient for the intended operating conditions.

Attenuators Selection Notes

Select this component when a compact form factor is required alongside high-frequency performance up to 30 GHz. The 4 dB attenuation value suits applications needing moderate signal reduction. Consider the 0805 package size relative to available board space. Verify that the 50 Ohm impedance matches the system design requirements for optimal signal integrity.

Attenuators Part Context

This part belongs to the ATS2012 series of high-frequency chip attenuators from Susumu. The series utilizes thin-film technology to achieve stable performance across a broad bandwidth. The 0805 package allows for automated surface-mount assembly, facilitating integration into modern electronic devices where size and performance are critical constraints.
