PAT1632-C-6DB-T1

Overview

The PAT1632-C-6DB-T1 is a fixed chip attenuator manufactured by Susumu, designed for surface-mount applications in the 1206 (3216 Metric) package. It provides a nominal attenuation of 6 dB with a 50 Ohm impedance across a frequency range from DC to 3 GHz. The component utilizes silicon technology and supports a maximum power dissipation of 125 mW. Key electrical specifications include a maximum Voltage Standing Wave Ratio (VSWR) of 1.3. The device operates within a temperature range of -55°C to +125°C and is supplied in tape and reel packaging.

Feature Summary

• Fixed 6 dB attenuation value suitable for precise signal level control
• Silicon-based construction ensuring stable performance up to 3 GHz
• Compact 1206 surface-mount footprint for automated assembly

Applications

• RF signal path conditioning in wireless communication systems
• Test and measurement equipment requiring precise attenuation
• Mobile device front-end modules operating at microwave frequencies

Procurement Notes

Verify the specific ordering suffix matches the required attenuation and tolerance. Confirm that the 1206 package dimensions align with the target PCB layout constraints. Ensure the 125 mW power rating is sufficient for the intended application's thermal environment. Check RoHS compliance status if restricted substances are prohibited in the final product design.

Selection Notes

Select this component when a 6 dB attenuation value is required within the 1206 package size. Consider the 125 mW power handling capability against the expected RF signal levels. Verify that the 3 GHz maximum frequency meets the operational bandwidth requirements. Evaluate the -55°C to +125°C temperature range against the environmental conditions of the deployment scenario.

Part Context

This part belongs to the Susumu PAT series of high-precision chip attenuators. The series offers various attenuation values and package sizes, including smaller footprints like 0402 and larger power-rated options. The PAT1632 variant specifically targets general-purpose RF applications requiring moderate power handling in a standard SMD form factor.

Replacement Considerations

Direct substitutes include other Susumu parts within the PAT series offering identical 6 dB attenuation and 1206 packaging, such as the PAT1632-C-3DB-T1 or PAT1632-C-10DB-T1, provided the specific attenuation value differs. Cross-brand replacements require matching impedance, frequency range, and power dissipation ratings.
