PE7048-3

Overview

The Pasternack PE7048-3 is a fixed RF attenuator designed for high-frequency applications up to 12.4 GHz. It provides a precise attenuation value of 3 dB with a characteristic impedance of 50 Ohms. The device features N-type male to N-type female connectors and utilizes a resistive PI pad design. It is housed in a black anodized aluminum heatsink body, enabling it to handle a maximum power rating of 10 Watts at the stated attenuation value across its operational frequency range.

Feature Summary

• Fixed 3 dB attenuation performance
• Operates from DC to 12.4 GHz
• N-type male to N-type female interface
• Black anodized aluminum heatsink construction

Applications

• RF signal level control in test and measurement setups
• Microwave circuit protection and power management
• Signal conditioning in communication systems

Procurement Notes

Verify the specific connector gender configuration (male-to-female) and physical dimensions against system requirements. Confirm that the 10 Watt power rating aligns with the intended operational environment. Ensure compatibility with standard N-type mating hardware. Check for any specific datasheet revisions or compliance documentation updates prior to final procurement decisions.

Selection Notes

Select this component when a fixed 3 dB reduction is required within the 12.4 GHz bandwidth. The 50 Ohm impedance matches standard RF infrastructure. The aluminum heatsink design supports higher power dissipation compared to non-heatsinked variants. Consider the N-type interface for robust mechanical connections in benchtop or permanent installations.

Part Context

This model belongs to the Pasternack PE7048 series of fixed coaxial attenuators. The series offers various attenuation values ranging from 1 dB to 30 dB, all sharing similar construction characteristics including the N-type interface and heatsink body. These components are engineered for consistent performance in microwave frequencies, providing reliable signal attenuation for precision applications.

Replacement Considerations

Compatible substitutes include other manufacturers' 3 dB fixed N-type attenuators rated for 12.4 GHz and 10 Watts. Verify that alternative parts maintain the same 50 Ohm impedance and physical mounting constraints. Ensure the replacement part meets the same VSWR and attenuation accuracy specifications documented for the original component.
