PE7046-3

Overview

The Pasternack PE7046-3 is a fixed RF attenuator designed for high-frequency applications. It provides an attenuation value of 3 dB with a nominal impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 40 GHz. It features a 2.92mm in-line module configuration, connecting a male connector on one side to a female connector on the other. The unit is constructed from passivated stainless steel and supports a maximum power handling capacity of 500 mW.

Feature Summary

• Fixed 3 dB attenuation performance
• Operates up to 40 GHz frequency range
• 2.92mm male-to-female interface
• Passivated stainless steel construction

Applications

• RF signal level reduction
• Impedance matching in microwave circuits
• Signal conditioning for high-frequency test equipment

Procurement Notes

Verify that the required attenuation value matches the specific application needs, as this model provides a fixed 3 dB loss. Confirm compatibility with the 2.92mm connector gender configuration, ensuring the system requires a male-to-female transition. Check that the operating frequency does not exceed the 40 GHz upper limit and that the power levels remain within the 500 mW rating to ensure reliable operation.

Selection Notes

Select this component when a precise 3 dB reduction is required in a 50 Ohm system. Ensure the design accommodates the 2.92mm interface standard rather than standard SMA or V-connectors. Consider the power handling limits relative to the expected signal strength. This model is suitable for environments requiring robust stainless steel housing and wideband frequency response up to 40 GHz.

Part Context

This part belongs to the Pasternack series of fixed RF attenuators. It utilizes the 2.92mm connector standard, which offers performance characteristics similar to the 3.5mm connector but with improved repeatability at higher frequencies. The in-line module format allows for direct integration into coaxial transmission lines without additional adapters.

Replacement Considerations

Direct substitutes must match the 3 dB attenuation, 50 Ohm impedance, and 2.92mm male-to-female interface. Verify that alternative components support the same 40 GHz frequency range and 500 mW power rating. Ensure physical dimensions and mounting requirements are compatible with the existing assembly.
