PAT1632-C-10DB-T1

Overview

The PAT1632-C-10DB-T1 is a silicon chip attenuator manufactured by Susumu, designed for surface-mount applications in the 1206 package size. It provides a fixed attenuation of 10 dB at a characteristic impedance of 50 Ohms. The device operates from DC to a maximum frequency of 3 GHz with a maximum VSWR of 1.3. It supports a power handling capacity of 125 mW and functions within an operating temperature range of -55°C to +125°C.

Feature Summary

• Fixed 10 dB attenuation value suitable for precise signal level control
• Silicon-based construction ensuring stable performance across wide temperature ranges
• Compact 1206 surface-mount footprint for automated PCB assembly

Applications

• RF signal path conditioning in wireless communication modules
• Impedance matching networks in test and measurement equipment
• Signal level adjustment in microwave circuit designs

Procurement Notes

Verify the specific suffix T1 against official Susumu documentation to confirm packaging configuration. Ensure the 1206 package dimensions align with the target PCB land pattern. Confirm that the 125 mW power rating meets the thermal requirements of the intended application environment without derating.

Selection Notes

Select this component when a fixed 10 dB reduction is required in a 50 Ohm system up to 3 GHz. Consider the 1206 size constraint for board space limitations. Evaluate the 125 mW power limit against peak signal levels to prevent thermal damage during operation.

Part Context

This part belongs to the Susumu PAT series of thin-film or silicon chip attenuators. These components are engineered for high reliability in RF and microwave circuits. The series offers various attenuation values and power ratings tailored for different frequency bands and power handling needs.

Replacement Considerations

Direct substitutes include other 10 dB, 50 Ohm, 1206 package attenuators from manufacturers like Mini-Circuits or Qorvo. Verify that replacement parts match the 3 GHz frequency limit and 125 mW power rating specifications.
