PE7022-40

Overview

The Pasternack PE7022-40 is a fixed 40 dB attenuator designed for RF applications. It operates from DC to 1.5 GHz with a nominal impedance of 50 Ohms. The device features SMA male to SMA female connectors and utilizes an in-line resistive PI attenuator pad design. It is rated for up to 100 W power handling and housed in a black anodized aluminum heatsink body.

Feature Summary

• Fixed attenuation value of 40 dB
• High power handling capability up to 100 W
• Frequency range extends from DC to 1.5 GHz
• Directional design with integrated aluminum heatsink

Applications

• RF signal level reduction
• Impedance matching in test setups
• Power measurement protection

Procurement Notes

Verify the specific datasheet version for precise VSWR and insertion loss values. Confirm connector gender and interface compatibility with existing system components. Ensure thermal management requirements are met given the 100 W rating. Check for any regional distribution restrictions or lead time variations before ordering.

Selection Notes

Select this model when a fixed 40 dB reduction is required within the 1.5 GHz bandwidth. The high power rating makes it suitable for high-power transmitter lines. The SMA interface ensures compatibility with standard coaxial systems. Consider the directional nature for proper signal flow orientation.

Part Context

This component belongs to the Pasternack PE7022 series of fixed attenuators. These devices are engineered for robust performance in demanding RF environments. The series offers various attenuation values and power ratings to suit different application needs while maintaining consistent impedance characteristics.

Replacement Considerations

Direct substitutes may include other 40 dB fixed attenuators with SMA interfaces and similar power ratings. Verify frequency response and physical dimensions for mechanical fit. Ensure equivalent VSWR and directivity specifications are maintained for critical applications.
