PE7357-10

Overview

The Pasternack PE7357-10 is a fixed 10 dB coaxial attenuator designed for in-line applications. It features an SMA male to SMA female interface and operates from DC to 18 GHz. The device handles up to 25 Watts of power at the stated attenuation value. Constructed with a black anodized aluminum heatsink body, it utilizes a resistive PI pad design within a 50 Ohm system.

Feature Summary

• Fixed 10 dB attenuation using a resistive PI pad topology
• SMA male to SMA female connector configuration
• Black anodized aluminum heatsink body for thermal management
• Operational frequency range extending to 18 GHz

Applications

• RF signal level reduction in microwave circuits
• Impedance matching between RF stages
• Protection of sensitive downstream components from high power

Procurement Notes

Verify the specific datasheet version for the PE7357-10 to confirm mechanical dimensions and detailed electrical tolerances. Ensure the SMA connectors match the mating hardware requirements. Confirm that the 25 Watt power rating aligns with the peak power conditions of the intended application environment.

Selection Notes

Select this component when a precise 10 dB loss is required across a wide bandwidth up to 18 GHz. The SMA interface suits standard laboratory and commercial RF setups. The heatsink body supports higher power dissipation compared to non-heatsink variants. Verify compatibility with existing SMA fixtures before integration.

Part Context

This model belongs to Pasternack's series of fixed coaxial attenuators. Similar models include PE7357-6 (6 dB), PE7357-3 (3 dB), and PE7357-20 (20 dB). All share the same 18 GHz frequency range, 25 Watt power handling, and SMA connector type, differing only in their attenuation values.

Replacement Considerations

Direct substitutes include other PE7357-series parts if different attenuation is acceptable. Generic SMA attenuators may replace it if they meet the 18 GHz and 25 Watt specifications. Verify connector gender and thread type compatibility.
