P1AT-18FF-67G2W-10

Overview

The P1AT-18FF-67G2W-10 is a precision high-frequency RF attenuator manufactured by P1dB Inc. It features a 1.85mm female-to-female in-line connector configuration and provides a fixed attenuation of 10 dB. The device operates across a frequency range from DC to 67 GHz with a maximum voltage standing wave ratio (VSWR) of 1.30. It supports a power handling capacity of 2 Watts and maintains a characteristic impedance of 50 Ohms. This component is designed for demanding microwave applications requiring stable signal reduction over an ultra-wide bandwidth.

Feature Summary

• Precision fixed attenuation value of 10 dB for consistent signal management
• Ultra-wideband operation extending from DC up to 67 GHz
• Robust 2-Watt power handling capability for high-power environments
• Low VSWR performance ensuring minimal signal reflection

Applications

• High-frequency test and measurement instrumentation
• Microwave communication system signal conditioning
• Defense and aerospace radar subsystems
• Satellite ground station equipment

Procurement Notes

Verify the specific part number suffix against official P1dB documentation to confirm the exact attenuation value and connector gender combination. Ensure that the 1.85mm interface compatibility matches your existing system hardware. Confirm RoHS compliance status if environmental regulations apply to your procurement requirements. Cross-reference the datasheet for any specific mounting or torque specifications required for installation.

Selection Notes

Select this component when a fixed 10 dB reduction is required within a 67 GHz operational envelope. The 1.85mm connector type dictates physical compatibility, so verify mating interfaces before ordering. Consider the 2-Watt power limit to ensure safe operation under expected load conditions. Evaluate the VSWR specification against system sensitivity requirements to maintain signal integrity.

Part Context

This model belongs to the P1AT series of coaxial attenuators from P1dB Inc. The series includes variants with different attenuation values, such as 3 dB and 6 dB options, all sharing similar 1.85mm connector geometries and wideband frequency characteristics. These components are engineered for high-reliability applications where precise signal control is critical across extreme frequency ranges.

Replacement Considerations

Compatible substitutes include other P1dB models within the same series, such as P1AT-18FF-67G2W-3 or P1AT-18FF-67G2W-6, provided the attenuation difference is acceptable. Verify that any replacement maintains the 1.85mm female-to-female interface and 50 Ohm impedance to ensure seamless integration without adapter usage.
