PE7024-20

Overview

The Pasternack PE7024-20 is a fixed 20 dB coaxial attenuator featuring 2.92mm male to 2.92mm female connectors. It operates from DC to 26.5 GHz with a 50 Ohm impedance. The unit is rated for 2 Watts maximum input power and maintains a VSWR of 1.3:1 up to 18 GHz, rising to 1.5:1 between 18 and 26.5 GHz. Attenuation accuracy is ±0.5 dB from DC to 18 GHz and ±1.0 dB from 18 to 26.5 GHz. The body is constructed from passivated stainless steel.

Feature Summary

• Utilizes a resistive PI pad design for stable attenuation performance across the frequency range.
• Features a robust passivated stainless steel body suitable for demanding RF environments.
• Supports bidirectional signal flow as a fixed, non-directional component.

Applications

• Microwave test and measurement setups requiring precise signal reduction
• RF circuit bias tees and power distribution networks
• Signal conditioning in high-frequency communication systems

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as 2.92mm interfaces are critical for maintaining impedance continuity at high frequencies. Confirm that the 2 Watt power rating aligns with the peak and average power levels of the application to prevent component damage. Ensure environmental conditions remain within the specified operational temperature range for optimal performance stability.

Selection Notes

Select this model when a fixed 20 dB reduction is required within the 26.5 GHz bandwidth. The 2.92mm interface offers superior performance compared to SMA or K-type connectors at these frequencies. Consider the stainless steel construction for durability if mechanical ruggedness is a priority over weight constraints in the assembly.

Part Context

This component belongs to the Pasternack fixed attenuator series, designed for consistent signal level management in RF systems. It serves as a passive interconnect device that dissipates excess power while maintaining impedance matching. The product line emphasizes reliability and precision for laboratory and industrial applications.

Replacement Considerations

Direct substitutes include other 20 dB fixed attenuators with 2.92mm male-to-female interfaces and similar 26.5 GHz ratings. Verify that alternative models match the 50 Ohm impedance and 2 Watt power handling capabilities to ensure functional equivalence without modifying the surrounding circuit topology.
