PE7322-50

Overview

The Pasternack PE7322-50 is a fixed RF attenuator designed for high-power applications. It provides a nominal attenuation of 50 dB with a frequency range extending from 0 Hz to 18 GHz. The device features N-type connectors, specifically a male connector on one side and a female connector on the other, facilitating in-line integration into coaxial systems. It is rated for a maximum power handling capacity of 50 Watts. The unit utilizes a black anodized aluminum heatsink body to ensure effective thermal management during operation. The impedance is standardized at 50 Ohms, ensuring compatibility with standard RF infrastructure.

Feature Summary

• Fixed 50 dB attenuation value for precise signal reduction

• Broad frequency performance from DC to 18 GHz
• Robust black anodized aluminum heatsink construction

Applications

• Production testing environments requiring stable signal levels
• RF system calibration and measurement setups
• High-power signal distribution networks
• Laboratory equipment for attenuation verification

Procurement Notes

Verify the specific datasheet version for the PE7322-50 to confirm mechanical dimensions and connector gender orientation prior to procurement. Ensure that the application environment does not exceed the 50 Watt power rating or 18 GHz frequency limit. Cross-reference the part number with official Pasternack documentation to distinguish between similar series models such as the PE7322-30 or PE7322-6, which share physical characteristics but differ in attenuation values and potentially frequency ranges. Confirm availability through authorized distributors.

Selection Notes

Select the PE7322-50 when a fixed 50 dB reduction is required in high-power RF circuits operating up to 18 GHz. This component is suitable for applications demanding robust thermal dissipation due to its 50 Watt rating. Consider this model over lower-power variants if the signal path involves significant power levels that could damage standard attenuators. The N-type interface ensures compatibility with existing coaxial cabling and test fixtures. Evaluate the need for directional versus non-directional performance based on system requirements, though this model is specified as directional.

Part Context

The PE7322-50 belongs to the Pasternack PE7322 series of fixed coaxial attenuators. This series offers various attenuation values ranging from 3 dB to 60 dB, all sharing a common form factor and connector type. The series is characterized by its use of N-type connectors and aluminum heatsink bodies, designed for durability and thermal efficiency. Other members include the PE7322-3, PE7322-6, and PE7322-30, providing options for different attenuation needs within the same physical package and power handling class.

Replacement Considerations

Direct substitutes may include other manufacturers' 50 dB fixed N-type attenuators rated for 50 Watts and 18 GHz. Verify that any replacement matches the exact attenuation value, power rating, and frequency response. Check for identical connector genders (Male-to-Female) and mounting style. Ensure the replacement maintains the 50 Ohm impedance characteristic.
