PE7393-10

Overview

The PE7393-10 is a fixed 10 dB attenuator manufactured by Pasternack. It operates within a frequency range of 0 Hz to 4 GHz and features an SMA male-to-SMA female interface. The device is designed for 50 Ohm systems and can handle up to 25 Watts of power. It utilizes a resistive PI pad design housed in an in-line module package.

Feature Summary

• Fixed 10 dB attenuation value
• SMA male to SMA female connector configuration
• Resistive PI pad internal design
• In-line module form factor

Applications

• RF signal level reduction
• Impedance matching in 50 Ohm systems
• Signal conditioning for microwave equipment

Procurement Notes

Verify the datasheet confirms the 10 dB specification, as some sources may list conflicting values like 30 dB. Ensure the SMA male-to-female orientation matches system requirements. Confirm the 25W power rating and 4GHz frequency limit are suitable for the intended application environment.

Selection Notes

Select this component when a precise 10 dB loss is required in a 50 Ohm RF circuit. The SMA interface offers compatibility with standard coaxial cables. Consider the 25W power handling capability for high-power applications. The in-line module design facilitates easy integration into existing setups.

Part Context

This part belongs to the PE7393 series of fixed attenuators from Pasternack. Other variants in the series include different attenuation values such as 3 dB, 20 dB, and 30 dB models. All share similar construction and interface types but differ in their specific loss characteristics.

Replacement Considerations

Compatible substitutes include other 10 dB SMA fixed attenuators from Pasternack or third-party manufacturers. Ensure replacement parts match the 50 Ohm impedance, 4 GHz frequency range, and 25W power rating. Verify connector gender and mating dimensions for mechanical compatibility.
