PE7357-6

Overview

The PE7357-6 is a fixed RF attenuator from Pasternack, designed for microwave applications up to 18 GHz. It features SMA male-to-female connectors and provides a precise attenuation value of 6 dB. The device supports a power rating of 25 Watts at the stated attenuation level. Constructed with a black anodized aluminum heatsink body, it ensures thermal stability during operation. The component operates within a frequency range of 0 Hz to 18 GHz and maintains a 50 Ohm impedance standard.

Feature Summary

• Provides fixed 6 dB attenuation for signal level control
• Operates effectively across a wide frequency range up to 18 GHz
• Supports high power handling capacity of 25 Watts
• Features durable black anodized aluminum heatsink construction

Applications

• Microwave signal testing and measurement systems
• RF instrumentation and laboratory equipment
• Telecommunications infrastructure components
• General-purpose test setups requiring signal reduction

Procurement Notes

Verify the specific connector gender configuration matches the SMA male-to-female requirement. Confirm that the 25 Watt power rating aligns with system thermal constraints. Ensure the 18 GHz maximum frequency covers all operational bandwidth needs. Check for RoHS compliance documentation if environmental regulations apply to the deployment environment.

Selection Notes

Choose this model when a precise 6 dB reduction is required in a 50 Ohm system. Select based on the need for high-frequency performance up to 18 GHz. Consider the physical size and heatsink design for integration into existing chassis. Validate that the SMA interface compatibility matches connected cables and devices.

Part Context

This part belongs to Pasternack's series of fixed coaxial attenuators. It shares design characteristics with other models in the PE7357 series, differing primarily in attenuation values such as 3 dB, 10 dB, or 40 dB. All variants typically maintain similar power ratings and frequency ranges while adjusting internal resistive elements to achieve specific loss values.

Replacement Considerations

Direct substitutes include other Pasternack models like PE7357-3 or PE7357-10 if different attenuation levels are acceptable. Cross-brand replacements must match the 50 Ohm impedance, SMA interface, and 18 GHz frequency limit. Verify that alternative parts support the same 25 Watt power handling capability.
