PAT0816-C-7DB-T5

Overview

The PAT0816-C-7DB-T5 is a high precision chip attenuator manufactured by Susumu, designed for RF and microwave applications. It provides an attenuation value of 7 dB with a nominal impedance of 50 Ohms. The device operates within a frequency range from DC to 10 GHz and features a maximum VSWR of 1.3. It has a power rating of 64 mW and utilizes silicon technology in a compact 0603 surface mount package. The component supports operation temperatures between -55°C and +125°C.

Feature Summary

• High precision attenuation performance suitable for sensitive RF signal paths
• Compact 0603 surface mount footprint for space-constrained designs
• Wide operational temperature range ensuring reliability in harsh environments

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise signal reduction
• Mobile device front-end modules for signal level adjustment

Procurement Notes

Verify the specific suffix T5 corresponds to the required packaging format, such as cut tape or reel, when placing orders. Confirm that the 7 dB attenuation tolerance meets the system requirements, as variations may exist across different production batches. Ensure compatibility with standard SMT assembly processes given the 0603 package dimensions.

Selection Notes

Select this component when a 7 dB fixed attenuation is required in a 50 Ohm system operating up to 10 GHz. The 0603 package offers a balance between size and power handling compared to smaller footprints. Consider the 64 mW power rating to ensure it exceeds the maximum expected signal power in the application path without thermal degradation.

Part Context

This part belongs to the PAT series of high precision chip attenuators from Susumu. The series includes various attenuation values and package sizes, such as the PAT1220 and PAT0510 variants. These components are categorized under wireless and RF integrated circuits, serving as passive elements for signal management in modern electronic devices.

Replacement Considerations

Direct substitutes include other 7 dB, 50 Ohm, 0603 chip attenuators from manufacturers like Mini-Circuits or Qorvo. Verify that alternative parts match the 10 GHz frequency limit and 64 mW power rating. Check if the replacement maintains the same VSWR specifications to ensure signal integrity is preserved.
