PE7390-30

Overview

The Pasternack PE7390-30 is a fixed coaxial attenuator designed for RF applications up to 3 GHz. It features N male to N female connectors with a 50 Ohm impedance. The unit provides a nominal attenuation of 30 dB and is rated for 5 Watts of power handling. Constructed with an aluminum body, it ensures reliable performance across a temperature range of -65°C to +125°C. The device maintains a typical VSWR of 1.15:1, supporting stable signal integrity in high-frequency circuits.

Feature Summary

• Provides precise 30 dB signal reduction for RF circuit management
• Utilizes durable aluminum construction for thermal stability
• Supports standard N-type connector interfaces for easy integration

Applications

• RF test and measurement equipment calibration
• Signal level adjustment in communication systems
• Protecting sensitive receiver inputs from high power levels

Procurement Notes

Verify the specific part number suffix against official datasheets to confirm connector gender and attenuation value. Ensure the operating frequency does not exceed 3 GHz and power requirements remain within the 5 Watt limit. Cross-reference manufacturer documentation for environmental specifications and mechanical dimensions prior to procurement.

Selection Notes

Select this component when a fixed 30 dB attenuation is required at frequencies up to 3 GHz. Consider the 5 Watt power rating and N-type interface compatibility with existing system infrastructure. Evaluate thermal management needs given the aluminum housing design for continuous operation in varying environmental conditions.

Part Context

This model belongs to Pasternack's series of fixed coaxial attenuators. These components are engineered for consistent performance in RF environments. The product line emphasizes reliability and precision for signal conditioning tasks in professional electronic systems.

Replacement Considerations

Compatible substitutes include models with identical 30 dB attenuation, N male/female interfaces, and 50 Ohm impedance. Verify that replacement units support the same 3 GHz frequency range and 5 Watt power rating to maintain system performance integrity.
