PE7357-50

Overview

The PE7357-50 is a fixed 50 dB RF attenuator from Pasternack, designed for in-line applications. It features SMA male to SMA female connectors and operates within a frequency range of 0 Hz to 6 GHz. The device maintains a 50 Ohm impedance and utilizes a resistive PI attenuator pad design. Constructed with a black anodized aluminum heatsink body, it supports power levels up to 25 Watts. This component provides precise signal attenuation for coaxial systems requiring stable performance across its specified bandwidth.

Feature Summary

• Fixed 50 dB attenuation value using a resistive PI pad topology
• SMA male to SMA female interface configuration
• Black anodized aluminum heatsink body for thermal management
• Coaxial 50 Ohm impedance design

Applications

• RF signal level reduction in test and measurement setups
• Protecting sensitive receiver inputs from high power signals
• Impedance matching and signal conditioning in coaxial circuits
• Attenuation stages in wireless communication infrastructure

Procurement Notes

Verify the specific connector gender and orientation against system requirements before ordering. Confirm that the 6 GHz upper frequency limit aligns with the operational bandwidth needs. Ensure the 25 Watt power handling capacity is sufficient for the intended application environment. Check for any specific mounting or thermal dissipation constraints related to the heatsink design.

Selection Notes

Select this model when a fixed 50 dB attenuation is required at frequencies up to 6 GHz. The SMA interface suits standard coaxial connections. Consider the 25 Watt power rating for high-power applications. The PI pad design offers consistent performance. Verify compatibility with existing SMA ports in the signal chain.

Part Context

This part belongs to Pasternack's series of fixed RF attenuators. It shares the same physical housing and connector style as other values in the PE7357 series, such as the PE7357-20 or PE7357-40. The primary distinction is the internal resistive network providing exactly 50 dB of loss. It is distinct from variable attenuators or those with different connector types like N-type.

Replacement Considerations

Direct substitutes include other 50 dB fixed attenuators with SMA male-to-female interfaces and similar power ratings. Models like the PE7356-50 offer similar attenuation but use N-type connectors, requiring adapter consideration. Ensure any replacement matches the 6 GHz frequency limit and 50 Ohm impedance.
