P1AT-SAMF-18G2W-10

Overview

The P1AT-SAMF-18G2W-10 is an in-line RF attenuator manufactured by P1dB Inc. It provides a fixed attenuation value of 10 dB with a frequency range extending from 0 Hz to 18 GHz. The component operates at a nominal impedance of 50 Ohms and supports a maximum power handling capacity of 2 Watts. It features SMA connectors, specifically configured as SMA male to SMA female, facilitating direct integration into coaxial transmission lines.

Feature Summary

• Provides fixed 10 dB signal attenuation across a wide bandwidth up to 18 GHz
• Utilizes SMA male-to-female interface for standard coaxial system compatibility
• Designed for in-line module mounting within RF signal paths

Applications

• RF signal level adjustment in wireless communication systems
• Test and measurement equipment requiring precise signal reduction
• Protecting sensitive receiver inputs from high-power signals

Procurement Notes

Verify the specific part number suffix against official P1dB Inc documentation to confirm connector gender and attenuation value. Ensure the operating environment stays within the specified 2W power limit and 18 GHz frequency range. Confirm that the SMA interface matches the existing system cabling requirements before procurement.

Selection Notes

Select this component when a fixed 10 dB attenuation is required at frequencies up to 18 GHz. The 50 Ohm impedance must match the system characteristic impedance to minimize reflections. Consider the 2W power rating relative to the maximum expected signal power in the application path to ensure reliable operation without damage.

Part Context

This model belongs to the P1AT series of RF attenuators from P1dB Inc. The series includes various attenuation values and frequency ranges, such as the P1AT-SAMF-18G2W-3 and P1AT-SAMF-18G2W-6. These components are designed for general-purpose RF applications requiring stable performance over broad bandwidths.

Replacement Considerations

Compatible substitutes include other P1AT-SAMF-18G2W-10 units from authorized distributors. Cross-brand replacements require matching 10 dB attenuation, 18 GHz frequency range, 50 Ohm impedance, 2W power rating, and SMA male-to-female connectivity.
