PAT-10+

Overview

The PAT-10+ is a surface-mount fixed attenuator manufactured by Mini-Circuits, designed for RF and microwave applications. It provides a nominal attenuation of 10 dB with a maximum frequency range extending from DC to 7 GHz. The component operates within a 50-ohm impedance system and features a compact SMD package with flat leads. It supports a power handling capacity of 1 Watt and maintains a maximum VSWR of 1.5. The device is rated for operation across a temperature range of -55°C to +100°C and complies with RoHS standards.

Feature Summary

• Fixed 10 dB attenuation value suitable for signal level control
• Broadband operational capability from DC up to 7 GHz
• Surface-mount technology (SMT) construction for automated assembly
• Robust thermal performance supporting high operating temperatures

Applications

• RF test and measurement equipment signal conditioning
• Wireless communication systems requiring precise attenuation
• Satellite communication downlink signal management
• Automotive radar system component integration

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required tolerance levels and termination styles. Confirm that the selected variant matches the intended PCB footprint and soldering profile. Cross-reference the RoHS compliance status with regional regulatory requirements before finalizing procurement orders to avoid supply chain disruptions.

Selection Notes

Select this component when a stable 10 dB attenuation is required in broadband RF circuits up to 7 GHz. Ensure the design accommodates the 50-ohm system impedance to minimize reflections. Consider the SMD package dimensions during PCB layout to maintain signal integrity. Verify that the 1W power rating aligns with the maximum expected signal levels in the application path to prevent thermal degradation.

Part Context

The PAT series represents Mini-Circuits' line of precision fixed attenuators utilizing thin-film hybrid technology. These components are engineered for consistent performance across wide bandwidths. The PAT-10+ specifically addresses needs for moderate signal reduction in compact form factors. This series complements other passive components like amplifiers and filters in complete RF front-end designs.

Replacement Considerations

Direct substitutes include other 10 dB fixed attenuators from Mini-Circuits such as the PAT-10 or variants with different mounting styles. Verify electrical parameters including attenuation accuracy, frequency range, and power handling. Check physical footprint compatibility for direct board replacement without redesigning the PCB layout.
