PE7370-40

Overview

The Pasternack PE7370-40 is a fixed coaxial attenuator designed for high-power RF applications. It provides an attenuation value of 40 dB within a frequency range of 0 Hz to 7.5 GHz. The component operates with a power rating of 25 Watts and maintains a system impedance of 50 Ohms. Constructed with a black anodized aluminum heatsink body, it ensures thermal stability during operation.

Feature Summary

• High power handling capability rated at 25 Watts
• Broadband frequency performance extending from DC to 7.5 GHz
• Robust thermal management via anodized aluminum heatsink construction

Applications

• RF signal level reduction in test and measurement setups
• Protection of sensitive receiver inputs from high power signals
• Integration into microwave systems requiring precise attenuation

Procurement Notes

Verify the specific connector interface configuration against your system requirements before ordering. Confirm that the 25 Watt power rating and 40 dB attenuation value align with your design specifications. Ensure compatibility with the 50 Ohm impedance environment. Check for any mechanical mounting constraints related to the heatsink body dimensions.

Selection Notes

Select this model when a fixed 40 dB attenuation is required for frequencies up to 7.5 GHz. Consider the 25 Watt power handling limit for high-power applications. The 50 Ohm impedance matches standard RF systems. Evaluate the physical size and mounting needs associated with the heatsink design compared to lower power alternatives.

Part Context

This component belongs to Pasternack's line of fixed coaxial attenuators. Similar models include PE7370-3 and PE7370-10, which offer different attenuation values such as 3 dB and 10 dB respectively. These parts share common design features like the aluminum heatsink body and 50 Ohm impedance but differ in their specific attenuation ratings and power handling capabilities.

Replacement Considerations

Direct substitutes may include other Pasternack models with identical 40 dB attenuation and 25 Watt ratings. Verify connector types match exactly. Cross-reference frequency ranges to ensure no degradation above 7.5 GHz. Ensure impedance remains 50 Ohms for system integrity.
