PE7388-30

Overview

The Pasternack PE7388-30 is a fixed RF attenuator designed for in-line applications. It provides a nominal attenuation of 30 dB across a frequency range of 0 Hz to 3 GHz. The component operates within a 50 Ohm impedance system and supports a power rating of up to 50 Watts. It features N-Type connectors, specifically an N Male input and an N Female output. The physical construction utilizes a black anodized aluminum heatsink body to manage thermal dissipation effectively during operation.

Feature Summary

• Unidirectional signal flow with N Male to N Female connector configuration
• Black anodized aluminum heatsink body for thermal management
• Fixed resistive PI attenuator pad design

Applications

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

Procurement Notes

Verify the specific datasheet version provided by Pasternack Enterprises, Inc., as specifications may vary between manufacturing batches. Confirm that the required power handling capacity of 50 Watts aligns with your system's peak power requirements. Ensure the operating frequency does not exceed 3 GHz to maintain specified attenuation accuracy. Check connector gender compatibility carefully, as this model is unidirectional with male-to-female interfaces.

Selection Notes

Select this component when a fixed 30 dB attenuation is required at frequencies up to 3 GHz. The 50 Watt power rating makes it suitable for moderate power applications where standard attenuators might overheat. The N-Type interface ensures compatibility with common coaxial systems. Consider the heatsink design if ambient temperature conditions are elevated or continuous duty cycles are expected.

Part Context

This part belongs to Pasternack's line of fixed RF attenuators, which offer precise attenuation values for various frequency ranges. The PE7388 series specifically targets applications requiring robust thermal performance due to its aluminum heatsink construction. These components are essential for maintaining signal integrity in RF circuits by reducing power levels to safe operating thresholds for downstream components.

Replacement Considerations

Pasternack PE7389-30 offers similar 30 dB attenuation and 50W rating but may differ in specific mechanical dimensions or connector tolerances. Verify exact interchangeability by comparing detailed mechanical drawings and electrical performance curves from official datasheets before substitution.
