PAT-15+

Overview

The PAT-15+ is a surface-mount fixed attenuator manufactured by Mini-Circuits, designed for RF applications operating from DC to 7 GHz. It provides a nominal attenuation of 15 dB with a characteristic impedance of 50 ohms. The device supports a maximum input power of 1 Watt and features a typical Voltage Standing Wave Ratio (VSWR) of 1.5. Packaged in the AF320 SMD form factor, it is available in cut tape, reel, and MouserReel formats, ensuring compatibility with automated surface-mount assembly processes.

Feature Summary

• Wideband operational capability spanning from DC to 7 GHz
• Excellent VSWR performance for signal integrity
• Surface-mount design compatible with standard PCB land patterns

Applications

• RF signal path attenuation in communication systems
• Impedance matching networks in microwave circuits
• Test and measurement equipment requiring precise signal reduction

Procurement Notes

Verify the specific packaging configuration required for production, as the component is available in cut tape, reel, and MouserReel options. Confirm that the AF320 footprint aligns with the target PCB layout. Ensure compliance with RoHS standards if environmental regulations apply to the final assembly. Cross-reference the datasheet for thermal handling requirements relative to the 1W power rating.

Selection Notes

Select this component when a fixed 15 dB attenuation is required within a wideband frequency range up to 7 GHz. The 50-ohm impedance ensures compatibility with standard RF infrastructure. Consider the surface-mount package for high-volume manufacturing efficiency. Evaluate the 1W power handling against the expected signal levels in the application circuit to prevent damage or performance degradation.

Part Context

The PAT series represents Mini-Circuits' line of fixed attenuators designed for broad frequency coverage. These components are engineered to provide stable attenuation values across their specified bandwidths. The PAT-15+ specifically addresses needs for significant signal reduction in compact RF modules, leveraging SMT technology for integration into modern electronic designs.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Verify that any alternative component matches the 15 dB attenuation value, 50-ohm impedance, and 7 GHz frequency limit. Ensure the replacement package type accommodates the existing PCB footprint without redesign.
