P1AT-18MF-67G2W-10

Overview

The P1AT-18MF-67G2W-10 is a coaxial RF attenuator manufactured by P1dB Inc. It provides a fixed attenuation of 10 dB with a frequency range extending from DC to 67 GHz. The component features a 50 Ohm impedance and supports a maximum power handling capacity of 2 Watts. Electrical performance includes a maximum Voltage Standing Wave Ratio (VSWR) of 1.30. The device utilizes 1.85mm connectors, specifically configured as male-to-female for inline integration.

Feature Summary

• Supports ultra-wideband operation from DC up to 67 GHz
• Maintains low VSWR of 1.30 maximum for signal integrity
• Handles continuous power loads up to 2 Watts

Applications

• High-frequency test and measurement instrumentation
• Millimeter-wave communication system calibration
• RF signal path power reduction in dense packaging

Procurement Notes

Verify the specific connector gender configuration matches the design requirement, as the model designation indicates male-to-female orientation. Confirm that the 1.85mm interface compatibility aligns with existing fixture standards. Ensure the 2W power rating satisfies peak and average thermal limits within the target application environment before finalizing procurement.

Selection Notes

Select this component when precise 10 dB attenuation is required at frequencies approaching 67 GHz. The 1.85mm interface offers superior performance over smaller connectors like 2.92mm or 2.4mm at these high frequencies. Consider the 2W power limit when designing for high-power signal chains to prevent component damage.

Part Context

This part belongs to the P1AT series of precision coaxial attenuators from P1dB Inc. The series is characterized by wide bandwidth capabilities and robust power handling. Variations in the suffix typically denote different attenuation values while maintaining the same 1.85mm connector type and 67 GHz frequency limit.

Replacement Considerations

Compatible substitutes include other 10 dB attenuators utilizing 1.85mm male-to-female interfaces with similar 67 GHz bandwidth and 2W power ratings. Verify mechanical dimensions and connector tolerances to ensure interchangeability without adapter requirements.
