PE70A1023

Overview

The PE70A1023 is a rotary step attenuator manufactured by Pasternack, designed for RF interconnect applications. It features SMA female connectors on both input and output ports. The device provides an attenuation range from 0 to 70 dB with discrete steps of 10 dB. It is rated for a maximum power handling of 2 Watts and operates within a frequency range up to 2.2 GHz. The unit weighs approximately 246.75 grams and is packaged in bulk.

Feature Summary

• Rotary mechanical adjustment mechanism for precise attenuation setting
• SMA female connector interface for standard coaxial integration
• Discrete 10 dB step resolution across the full attenuation range

Applications

• RF signal level control in test and measurement equipment
• Attenuation stages in wireless communication systems
• Calibration setups requiring known signal reduction values

Procurement Notes

Verify that the required attenuation steps align with the 10 dB increments provided by this model. Confirm that the operating frequency does not exceed 2.2 GHz and that the signal power remains within the 2 Watt rating. Ensure SMA female connectors are compatible with the existing system cabling. Check RoHS compliance requirements if applicable to your manufacturing standards.

Selection Notes

Select this component when fixed step attenuation is preferred over continuous variable adjustment. The 10 dB step size offers a balance between precision and simplicity for coarse signal leveling. Consider the physical dimensions and weight for enclosure space constraints. This model is suitable for applications where manual rotary adjustment is acceptable and digital control is not required.

Part Context

This part belongs to the Pasternack RF Variable Attenuators series, specifically categorized under Connectorized Attenuators. It is distinct from variable or fixed attenuators due to its stepped rotary design. The product line generally supports frequencies up to 18 GHz and power ratings from 2W to 5W, but this specific model is limited to 2.2 GHz.

Replacement Considerations

No direct substitute part numbers are publicly confirmed in the provided documentation. Similar models in the series may offer different step sizes or connector types. Verify compatibility carefully if replacing with other Pasternack attenuators.
