PE7390-3

Overview

The Pasternack PE7390-3 is a fixed attenuator designed for RF applications up to 3 GHz. It features N-type connectors with male gender on one side and female gender on the other, facilitating direct inline integration into coaxial systems. The unit is constructed with an aluminum body for durability and thermal management. It provides a precise attenuation value of 3 dB while maintaining a 50 Ohm impedance characteristic. The device is rated to handle up to 5 watts of power, ensuring reliable operation in moderate signal environments.

Feature Summary

• Fixed 3 dB attenuation performance
• N-type male to female connector interface
• Aluminum housing construction
• 50 Ohm system impedance

Applications

• RF signal level reduction
• Test and measurement setups
• Communication system integration
• Impedance matching networks

Procurement Notes

Verify that the required attenuation value matches the specific application needs, as this model provides a fixed 3 dB loss. Confirm compatibility with existing N-type connectors in the signal chain. Ensure the operating frequency does not exceed 3 GHz and that the power handling requirement stays within the 5-watt limit. Check for any specific environmental ratings if the deployment involves extreme temperatures or harsh conditions.

Selection Notes

Select this component when a precise 3 dB reduction is required without variable adjustment capabilities. It is suitable for systems utilizing N-type interfaces where robust aluminum construction is preferred over plastic alternatives. Consider the 5-watt power rating to ensure it aligns with the maximum signal levels present in the circuit. This model is ideal for fixed-loss applications rather than those requiring dynamic attenuation control.

Part Context

This part belongs to Pasternack's line of fixed attenuators, which are essential passive components in RF engineering. These devices are used to reduce signal amplitude without introducing significant distortion or reflection. The PE7390 series specifically utilizes N-type connectors, a standard choice for frequencies up to several gigahertz due to their mechanical stability and low loss characteristics compared to smaller connectors.

Replacement Considerations

Compatible substitutes include other 3 dB fixed attenuators from Pasternack with N-type connectors, such as the PE7390-1 or PE7390-6, depending on the required attenuation value. Ensure replacement parts maintain the same 50 Ohm impedance and 3 GHz frequency range. Verify that the power handling capability meets or exceeds the original 5-watt specification.
