PE7047-8

Overview

The PE7047-8 is a fixed RF attenuator manufactured by Pasternack, designed for in-line signal reduction applications. It provides an attenuation value of 8 dB with a frequency range extending from 0 Hz to 12.4 GHz. The component features N-type connectors, specifically N Male to N Female interfaces, ensuring compatibility with standard coaxial systems. It operates within a 50 Ohm impedance environment and is rated for a maximum power handling capacity of 2 Watts. The physical construction utilizes a passivated stainless steel body, offering durability and environmental resistance suitable for high-frequency test and measurement setups.

Feature Summary

• Fixed 8 dB attenuation performance across a wide frequency spectrum up to 12.4 GHz
• N Male to N Female connector configuration for direct coaxial integration
• Passivated stainless steel housing for structural integrity and corrosion resistance
• 2 Watt power rating supporting continuous operation in standard RF environments

Applications

• RF signal level adjustment in test and measurement instrumentation
• Impedance matching and signal conditioning in wireless communication systems
• Protection of sensitive receiver inputs from high-power signals
• Calibration procedures requiring precise attenuation steps

Procurement Notes

Verify the specific datasheet version provided by Pasternack Enterprises to confirm current manufacturing specifications and compliance standards. Ensure that the N-type connector gender and mating requirements align with existing system infrastructure before procurement. Confirm that the 2 Watt power rating is sufficient for the intended operational duty cycle to prevent thermal degradation. Check for any regional distribution restrictions or lead time variations associated with this specific part number through authorized channels.

Selection Notes

Select the PE7047-8 when a fixed 8 dB attenuation is required within the DC to 12.4 GHz bandwidth. This model is appropriate for applications necessitating robust stainless steel construction and standard N-type connectivity. Consider alternative models such as PE7047-20 or PE7047-40 if different attenuation values are needed while maintaining the same form factor and connector type. Ensure the operating frequency does not exceed 12.4 GHz to maintain specified performance characteristics.

Part Context

The PE7047-8 belongs to the Pasternack PE7047 series of fixed attenuators, which includes variants with different attenuation values like 20 dB and 40 dB. These components share a common design philosophy focusing on reliable performance in high-frequency applications. The series utilizes passivated stainless steel bodies and N-type connectors, providing a standardized solution for RF engineers requiring consistent impedance and mechanical stability across various signal processing tasks.

Replacement Considerations

Direct substitutes include other Pasternack models within the PE7047 series, such as PE7047-20 or PE7047-40, if different attenuation levels are acceptable. Ensure that any replacement maintains the N Male to N Female interface and 50 Ohm impedance. Verify that the power rating and frequency range of the substitute meet or exceed the original requirements.
