PE70A2004

Overview

The Pasternack PE70A2004 is a high-reliability absorptive voltage variable attenuator designed for operation within the 20 GHz to 50 GHz frequency range. It provides a maximum attenuation of 40 dB with a characteristic impedance of 50 Ohms. The device utilizes a 2.4mm connector interface and is constructed as an in-line module. This component is engineered to reduce the amplitude level of incoming signals while maintaining performance at microwave frequencies.

Feature Summary

• Absorptive design for signal amplitude reduction
• Voltage-controlled variable attenuation mechanism
• High-reliability construction for demanding environments

Applications

• Microwave test and measurement systems
• Signal processing applications requiring precise amplitude control
• Radar and communication subsystems operating in the K-band and above

Procurement Notes

Verify that the specific application requires a voltage-variable attenuator rather than a fixed or step-type alternative. Confirm compatibility with the 2.4mm connector interface and ensure the system can support the required control voltages. Check for any specific environmental ratings if the deployment involves extreme temperatures or vibration, as standard specifications may vary by production batch.

Selection Notes

Select this model when continuous analog attenuation is necessary across the 20-50 GHz spectrum. The 40 dB range accommodates significant signal power adjustments. Ensure the host system has adequate thermal management capabilities, as absorptive attenuators dissipate excess RF energy as heat. Validate that the 50 Ohm impedance matches all connected components to minimize reflections.

Part Context

This component belongs to Pasternack's RF Variable Attenuators series, specifically targeting high-frequency microwave applications. Unlike step attenuators which offer discrete values, this unit provides smooth, continuous adjustment via an external voltage input. It serves as a critical active element in systems requiring dynamic signal level management at ultra-high frequencies.

FAQ

What type of attenuation technology does the PE70A2004 use?

It uses an absorptive technology, which dissipates excess RF energy as heat rather than reflecting it back to the source.

How is the attenuation level controlled?

The attenuation is controlled via an external voltage input, allowing for continuous variable adjustment rather than discrete steps.
