PE7313-20

Overview

The Pasternack PE7313-20 is a fixed RF attenuator designed for high-power microwave applications. It provides a precise attenuation value of 20 dB across a frequency range of 0 Hz to 7.5 GHz. The component features 7/16 DIN female connectors on both input and output ports, ensuring compatibility with standard industrial coaxial systems. Constructed with a black anodized aluminum heatsink body, it supports a maximum power rating of 50 Watts at the stated attenuation level. The unit maintains a typical voltage standing wave ratio (VSWR) of 1.45:1, offering stable signal performance in demanding environments.

Feature Summary

• High power handling capability rated at 50 Watts
• Broadband operation from DC to 7.5 GHz
• Integrated heatsink design for thermal management
• Robust 7/16 DIN connector interface

Applications

• Microwave test and measurement setups
• Telecommunications infrastructure signal conditioning
• Radar system power monitoring circuits
• RF equipment calibration and testing

Procurement Notes

Verify that the specific order matches the PE7313-20 designation to ensure correct 7/16 DIN female-to-female configuration. Confirm that the application environment does not exceed the 50 Watt power limit or 7.5 GHz frequency cap. Check for RoHS compliance documentation if required by project specifications. Ensure proper torque values are applied during installation to maintain seal integrity and electrical performance.

Selection Notes

Select this model when a 20 dB attenuation value is required within the 7.5 GHz bandwidth. Choose this part over lower-rated models if the circuit involves power levels approaching 50 Watts. The 7/16 DIN interface makes it suitable for applications requiring larger connectors than SMA or N-type. Consider the heatsink body as a key factor for maintaining performance under continuous high-power loads compared to smaller form-factor attenuators.

Part Context

This component belongs to Pasternack's line of fixed RF attenuators, which are passive devices used to reduce signal amplitude without distortion. The PE7313 series specifically targets high-power applications using 7/16 DIN interfaces. These attenuators are essential for protecting sensitive downstream components from excessive signal power while maintaining impedance matching and low reflection characteristics across the specified frequency range.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. When replacing, ensure the new component matches the 20 dB attenuation, 7.5 GHz frequency range, 50 Watt power rating, and 7/16 DIN female connector type. Verify that any alternative part offers equivalent VSWR and thermal dissipation capabilities.
