PE7393-20

Overview

The Pasternack PE7393-20 is a fixed RF attenuator with a nominal attenuation value of 20 dB. It operates within a frequency range of 0 Hz to 4 GHz and maintains a characteristic impedance of 50 Ohms. The device is rated for a maximum power handling capacity of 25 Watts at the specified attenuation level. It features SMA male input and SMA female output connectors, designed for inline module applications in microwave systems.

Feature Summary

• Provides precise 20 dB signal reduction across a wide bandwidth up to 4 GHz
• Engineered for high power handling capability of 25 Watts
• Utilizes durable black anodized construction for environmental resistance
• Features standard SMA gendered connectors for direct inline integration

Applications

• Microwave system signal level adjustment
• RF test and measurement setups requiring fixed attenuation
• Communication equipment signal conditioning
• Antenna feed line power management

Procurement Notes

Verify the specific datasheet version for the PE7393-20 to confirm connector gender orientation and exact physical dimensions. Ensure that the operating environment temperature and humidity levels remain within the manufacturer's specified limits for long-term reliability. Cross-reference the 25W power rating against actual continuous wave (CW) and peak pulse requirements in your specific application circuit to prevent thermal damage.

Selection Notes

Select the PE7393-20 when a fixed 20 dB loss is required in a 50-Ohm system operating below 4 GHz. Consider this model over adjustable attenuators if stability and repeatability are prioritized over tunability. Verify that the SMA interface compatibility matches existing cabling and fixture standards. Evaluate the 25W power rating against peak signal levels to ensure adequate safety margins during transient events.

Part Context

This component belongs to Pasternack's series of fixed microwave attenuators designed for reliable signal control. The PE7393 series offers various attenuation values while maintaining consistent performance characteristics across the family. These devices are engineered for use in demanding RF environments where precise signal attenuation is critical for system integrity and protection of downstream components.

Replacement Considerations

Direct substitutes include other 20 dB fixed attenuators from Pasternack with compatible interfaces, such as the PE7424-20 which uses Type N connectors but shares similar electrical specifications. When replacing, ensure the new component matches the 50-Ohm impedance and 4 GHz frequency limit. Verify that the power handling capabilities of the replacement part meet or exceed the original 25W rating.
