P1AT-18FF-67G2W-3

Overview

The P1AT-18FF-67G2W-3 is a precision high-frequency RF attenuator manufactured by P1dB Inc. It features a 1.85mm female-to-female in-line module configuration. The component provides a fixed attenuation value of 3 dB across a frequency range of 0 Hz to 67 GHz. It supports a maximum power handling capacity of 2 Watts. The device is designed for applications requiring stable signal reduction in ultra-wideband microwave systems.

Feature Summary

• Precision high-frequency RF attenuation with fixed 3 dB loss
• Ultra-wideband operation extending from DC to 67 GHz
• Robust 1.85mm female-to-female in-line modular interface
• High power handling capability rated at 2 Watts

Applications

• Ultra-wideband microwave test and measurement setups
• Signal conditioning in high-frequency communication systems
• Calibration equipment requiring precise attenuation levels
• Radar system signal path management

Procurement Notes

Verify the specific part number suffix against official P1dB Inc documentation to confirm connector gender and attenuation value. Ensure compatibility with 1.85mm interfaces in your assembly. Request manufacturer datasheets for detailed VSWR and insertion loss specifications before integration. Confirm active status and availability through authorized channels.

Selection Notes

Select this component when a fixed 3 dB attenuation is required within a 67 GHz bandwidth. The 1.85mm female-to-female interface dictates mating connector requirements. Consider the 2 Watt power rating for thermal management in high-power signal paths. Verify impedance matching and physical dimensions against system constraints.

Part Context

This model belongs to the P1AT series of precision RF attenuators from P1dB Inc. The series offers various attenuation values and connector configurations for high-frequency applications. The 1.85mm interface supports operations up to 67 GHz, distinguishing it from lower-frequency SMA or 2.92mm variants. This specific variant provides a standard 3 dB reduction.

Replacement Considerations

Compatible substitutes include models with identical 1.85mm female-to-female interfaces and 3 dB attenuation ratings. Check for equivalent power handling capabilities around 2 Watts. Verify that alternative parts maintain the same 0 Hz to 67 GHz frequency range. Ensure mechanical dimensions match existing mounting requirements.
