PE7312-40

Overview

The PE7312-40 is a fixed 40 dB attenuator manufactured by Pasternack. It features a 7/16 DIN male to 7/16 DIN female interface configuration. The device is rated for operation up to 7.5 GHz with a power handling capacity of 50 watts. Constructed as an in-line, resistive PI attenuator pad design, it operates within a 50 Ohm impedance system. The unit utilizes a hexagonal module form factor suitable for direct integration into RF test and measurement setups requiring precise signal reduction.

Feature Summary

• In-line resistive PI attenuator pad design
• Hexagonal module form factor for secure mounting
• Rated for high power handling up to 50 watts

Applications

• RF and microwave test and measurement systems
• Signal level reduction in high-power transmission lines
• Calibration and characterization of RF components

Procurement Notes

Verify the specific datasheet version for the PE7312-40 to confirm mechanical dimensions and connector gender orientation prior to integration. Ensure that the operating frequency range up to 7.5 GHz aligns with system requirements. Confirm thermal management capabilities are sufficient for continuous 50-watt dissipation in the intended enclosure environment.

Selection Notes

Select this component when a fixed 40 dB attenuation value is required at 7/16 DIN interfaces. The 50-watt rating distinguishes it from lower-power variants. Consider the hexagonal body shape for tool-assisted installation in dense rack environments. Verify compatibility with existing 50 Ohm infrastructure to maintain impedance matching.

Part Context

This model belongs to Pasternack's line of coaxial fixed attenuators designed for robust RF applications. It complements other attenuator series such as the PE7512-40, which offers similar attenuation but with different connector types or power ratings. The product family focuses on providing reliable signal control across various frequency bands using standardized connector interfaces.

Replacement Considerations

Direct substitutes include models with identical 40 dB attenuation and 7/16 DIN interfaces, such as the PE7310-40 if frequency limitations are acceptable. Verify that any replacement maintains the 50-watt power rating and 50 Ohm impedance to ensure circuit integrity without modification.
