PAT-9+

Overview

The Mini-Circuits PAT-9+ is a surface-mount fixed RF attenuator designed for applications requiring precise signal reduction. It provides a nominal attenuation of 9 dB across a frequency range from DC to 7000 MHz (7 GHz). The component operates with a characteristic impedance of 50 Ohms and supports a maximum power rating of 1 Watt. Housed in a compact 4-SMD, flat lead package, it is optimized for integration into space-constrained printed circuit boards within radio frequency and microwave systems.

Feature Summary

• Provides fixed 9 dB attenuation for consistent signal level control
• Operates effectively from DC up to 7000 MHz
• Designed for surface-mount technology with a compact footprint
• Maintains 50 Ohm impedance matching for standard RF interfaces

Applications

• RF signal path conditioning in communication equipment
• Test and measurement instrumentation setups
• Microwave circuit board integration
• Receiver input protection stages

Procurement Notes

Verify the specific ordering suffix required for your packaging preference, such as tape and reel or cut tape, when placing orders. Confirm that the voltage and power ratings align with your system's operational limits. Ensure compatibility with your PCB layout regarding the 4-SMD flat lead package dimensions. Check for any RoHS compliance requirements if applicable to your manufacturing standards.

Selection Notes

Select this component when a fixed 9 dB reduction is necessary within the 0 Hz to 7 GHz bandwidth. Consider the 1W power handling capability relative to your signal levels. The SMT form factor suits automated assembly processes. Evaluate the physical size constraints against other available attenuator values in the same series to ensure optimal board space utilization.

Part Context

This part belongs to the Mini-Circuits PAT+ series of miniature surface-mount attenuators. These components are engineered for high reliability in RF and microwave environments. The series offers various attenuation values while maintaining consistent electrical performance across wide frequency bands, supporting diverse design needs in modern electronic systems.

Replacement Considerations

Direct substitutes include other Mini-Circuits PAT+ series models with different attenuation values, such as PAT-6+, PAT-10+, or PAT-20+, provided the specific dB value meets the circuit requirements. Cross-brand replacements require careful verification of impedance, frequency range, and power handling specifications.
