PE70A1025

Overview

The PE70A1025 is a rotary step attenuator manufactured by Pasternack, featuring SMA female connectors on both ends. It provides an attenuation range from 0 to 25 dB with 5 dB steps. The device operates within a frequency range of DC to 2.2 GHz and supports a maximum power rating of 2 Watts. It maintains a 50 Ohm impedance system.

Feature Summary

• Provides discrete attenuation levels via a rotary switch mechanism
• Utilizes SMA female-to-female connector configuration for direct integration
• Designed for operation up to 2.2 GHz with 2 Watt power handling

Applications

• RF signal path attenuation in test and measurement setups
• Signal level adjustment in communication systems
• Component testing requiring variable load conditions

Procurement Notes

Verify the specific datasheet version for the PE70A1025 to confirm current RoHS compliance status and detailed mechanical dimensions. Ensure that the required attenuation steps align with the 5 dB increment design. Confirm that the 2 Watt power rating is sufficient for the intended application environment before finalizing procurement.

Selection Notes

Select this model when precise 5 dB step adjustments are required within the 0 to 25 dB range. It is suitable for applications operating below 2.2 GHz where SMA connectivity is standard. Consider the 2 Watt power limit and ensure the physical form factor fits the assembly constraints compared to higher-power or broader-bandwidth alternatives.

Part Context

This component belongs to the Pasternack RF Variable Attenuators series, specifically designed as a connectorized attenuator. It falls under the subcategory of general attenuators used for signal control. The product is part of a lineup offering various step configurations and power ratings for different RF requirements.

Replacement Considerations

Check for equivalent models with identical SMA female interfaces and similar 5 dB step increments. Verify that replacement units support the same 2.2 GHz frequency limit and 2 Watt power rating to maintain system performance integrity.
