PE7090-3

Overview

The Pasternack PE7090-3 is a fixed RF attenuator designed for high-frequency applications. It provides a nominal attenuation of 3 dB with a tolerance of ±1 dB. The component operates over a frequency range from DC to 40 GHz, supporting signals up to 2 Watts continuous wave (CW). It features a 50 Ohm impedance and utilizes 2.92mm connectors, specifically male-to-female configuration. The housing is constructed from passivated stainless steel to ensure durability and signal integrity in demanding environments.

Feature Summary

• Bidirectional signal handling capability
• Ultra-wideband operation extending to 40 GHz
• Robust passivated stainless steel construction

Applications

• RF instrumentation systems
• Signal testing and measurement setups
• High-frequency circuit calibration

Procurement Notes

Verify the specific connector gender configuration matches the design requirements, as this model specifies male-to-female interfaces. Confirm that the 2 Watt power rating aligns with the maximum expected signal levels in the application to prevent damage. Ensure the 40 GHz frequency range covers the operational bandwidth needs. Check for RoHS compliance status if environmental regulations apply to the project.

Selection Notes

Select this component when precise 3 dB attenuation is required at frequencies approaching 40 GHz. The 2.92mm interface offers superior performance compared to standard SMA or N-type connectors at these high frequencies. Consider the bidirectional nature for flexible placement within transmission lines. The stainless steel body provides mechanical stability suitable for benchtop or integrated test fixtures.

Part Context

This part belongs to the PE7090 series of fixed attenuators from Pasternack. The series includes various attenuation values such as 1, 3, 6, 10, and 30 dB, all sharing similar high-frequency characteristics and connector types. These components are engineered for consistency across different attenuation levels within the same physical form factor.

Replacement Considerations

Direct substitutes include other PE7090 series models with different attenuation values if the dB requirement changes. Generic 2.92mm fixed attenuators from other manufacturers may serve as alternatives if electrical specifications match exactly. Verify that any replacement maintains the 40 GHz upper frequency limit and 50 Ohm impedance.
