P1AT-18MF-67G2W-1

Attenuators Overview

The P1AT-18MF-67G2W-1 is a fixed coaxial RF attenuator manufactured by P1dB Inc. It provides a nominal attenuation of 1 dB with an operating frequency range from DC to 67 GHz. The component features a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 2 Watts. Electrical performance includes a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1. The device utilizes 1.85mm connectors, specifically a male connector on one end and a female connector on the other, ensuring compatibility with high-frequency test and measurement systems.

Attenuators Feature Summary

• Supports ultra-wideband operation extending up to 67 GHz for millimeter-wave applications
• Utilizes precision 1.85mm gendered connectors for secure high-frequency signal transmission
• Maintains low reflection characteristics with a maximum VSWR of 1.35:1 across the frequency band

Attenuators Applications

• High-frequency signal generation and testing equipment
• Millimeter-wave communication system calibration
• Vector network analyzer extension modules

Attenuators Procurement Notes

Verify the specific attenuation value matches the required circuit design, as this model provides 1 dB loss. Confirm that the 1.85mm connector interface aligns with existing test fixtures. Ensure the 2 Watt power rating is sufficient for the intended signal levels. Check RoHS compliance status if environmental regulations apply to the assembly process. Validate the VSWR specification against system return loss requirements.

Attenuators Selection Notes

Select this component when a precise 1 dB attenuation is required at frequencies approaching 67 GHz. The 1.85mm interface is necessary for maintaining signal integrity in ultra-high-frequency environments where larger connectors introduce excessive loss or reflection. Consider the 50 Ohm impedance match for standard RF systems. Evaluate the 2 Watt power limit to ensure safe operation under continuous wave conditions without thermal degradation.

Attenuators Part Context

This part belongs to the P1AT series of fixed coaxial attenuators from P1dB Inc. The series offers various attenuation values while maintaining consistent electrical performance across the DC to 67 GHz range. These components are designed for use in high-performance RF and microwave test setups. The specific suffix indicates the 1.85mm connector type and 2 Watt power rating common to this product line.

Attenuators Replacement Considerations

Direct substitutes include other P1AT models with identical 1.85mm interfaces and 67 GHz frequency limits but different attenuation values, such as P1AT-18MF-67G2W-3 or P1AT-18MF-67G2W-6. Cross-manufacturer replacements must match the 1.85mm connector geometry, 50 Ohm impedance, and 67 GHz upper frequency limit to ensure mechanical and electrical compatibility.
