PE7371-20

Overview

The Pasternack PE7371-20 is a fixed coaxial RF attenuator module designed for in-line applications. It provides a nominal attenuation of 20 dB with a frequency range extending from 0 Hz to 18 GHz. The component features N-Type female connectors on both input and output ports, ensuring compatibility with standard N-Type cabling systems. Constructed with a black anodized aluminum heatsink body, it is rated to handle up to 25 Watts of power. The unit maintains a 50 Ohm impedance throughout its operational bandwidth.

Feature Summary

• Fixed 20 dB attenuation value
• Operates up to 18 GHz frequency
• N-Type female connector interface
• 25 Watt power handling capability

Applications

• RF signal level reduction in test and measurement setups
• Protection of sensitive receiver inputs from high power signals
• Impedance matching in microwave communication circuits

Procurement Notes

Verify the specific model suffix to confirm the exact attenuation value and connector type before ordering. Ensure that the operating environment temperature remains within the specified limits for the 25 Watt rating. Confirm that the N-Type interface matches the existing system cabling requirements to avoid adapter usage.

Selection Notes

Select this model when a precise 20 dB reduction is required across a wide bandwidth up to 18 GHz. The robust aluminum heatsink design supports higher power dissipation compared to smaller surface-mount alternatives. Consider the physical size and mounting requirements associated with the inline module form factor during system integration planning.

Part Context

This component belongs to Pasternack's series of fixed coaxial attenuators. These modules are engineered for stability and repeatability in RF environments. The N-Type interface is widely used in industrial and telecommunications applications due to its durability and reliable performance at high frequencies.

Replacement Considerations

Compatible substitutes include other 20 dB fixed attenuators with N-Type female connectors and similar power ratings. Verify that replacement units maintain the same 50 Ohm impedance and frequency response characteristics to ensure circuit continuity.
