PE7317-20

Overview

The Pasternack PE7317-20 is a fixed RF attenuator module designed for high-frequency applications. It provides a nominal attenuation of 20 dB across a frequency range of 0 Hz to 18 GHz. The component features N-type connectors, specifically an N-female interface on side one and an N-male interface on side two. It operates with a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 50 Watts. The unit utilizes a directional black anodized aluminum heatsink body for thermal management.

Feature Summary

• Directional design utilizing a black anodized aluminum heatsink body for effective thermal dissipation
• Capable of maintaining signal integrity within the 0 Hz to 18 GHz operational bandwidth
• Supports high-power transmission environments up to 50 Watts continuous power rating

Applications

• RF test and measurement instrumentation setups
• Telecommunications equipment signal conditioning
• General-purpose laboratory testing requiring precise signal reduction

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as this model specifies N-female to N-male interfaces. Confirm that the 50-watt power rating aligns with the peak and average power levels present in the target circuit. Ensure the operating frequency does not exceed the 18 GHz upper limit to maintain specified attenuation accuracy and VSWR performance.

Selection Notes

Select this component when a fixed 20 dB reduction is required at frequencies extending up to 18 GHz. The choice is appropriate for systems utilizing N-type connectors where a 50-ohm impedance match is necessary. Consider the physical dimensions and mounting requirements associated with the heatsink body to ensure compatibility with the installation environment.

Part Context

This part belongs to the Pasternack PE7317 series of fixed attenuators. The series includes variants with different attenuation values, such as 6 dB, 10 dB, and 30 dB options. All models in this line share similar construction characteristics, including the use of N-type connectors and a common 50-watt power handling capability.

Replacement Considerations

Compatible substitutes include other 20 dB fixed attenuators from Pasternack with matching N-type interfaces, such as the PE7317-20LF variant if lead-free compliance is required. Cross-manufacturer replacements must verify identical 50-ohm impedance, 18 GHz frequency range, and 50-watt power rating.
